In recent years, with the rapid development of modern information technology, intelligent algorithms have been deeply embedded in all aspects of social life, which not only promotes the continuous development of human economy and society to intelligence, but also promotes the overall pattern of society to intelligence, providing technical guidance for the efficient and orderly operation of national governance and becoming an important driving force for the modernization of national governance level and governance capacity. In this context, how to promote the algorithm technology to be more effectively embedded in government governance at this stage, how to counter the origin of technology while giving full play to technical benefits, and how to better achieve the goal of maximizing public value become an urgent proposition of the times. In this paper, an analytical framework is built from the three dimensions of "technology-power-rules" to study the embedding of algorithms into government governance. Taking the practice of embedding algorithms into different scenes of government governance as the observation window, the operational logic and value implication of enabling government governance by algorithms are explored, and it is proposed that algorithm technology can promote public decision-making to be more rational, algorithm power can promote governance behavior to be more inclusive, and algorithm rules can promote government governance to be more fair. At the same time, it focuses on the risks and challenges that may be brought by the application of algorithms with technical, power and rule attributes in government governance practice, such as the black box of algorithm technology blocking the identification of public responsibility, the power of algorithm weakening the autonomy of government and people, and the preference of algorithm rules leading to the loss of governance justice. Combined with the government governance practice in China, it is proposed that in order to promote the intelligent algorithm to be more effectively embedded in government governance and better realize the goal of maximizing public benefits, efforts should be made to promote the moderate transparency of algorithm technology to clarify the chain of responsibility, standardize the operation of algorithm power and adhere to the humanistic governance concept. Different from the "negative theory of algorithm" and "positive theory of algorithm" held by the existing research results, this paper recognizes that the algorithm has both positive and negative external benefits to government governance from the two dimensions of efficiency and value, and focuses on how to avoid or reduce the possible risks and challenges of the algorithm to government governance from the three levels of technology, power and rules, and amplify the positive benefits of the algorithm to the governance process, so that the intelligent algorithm can be truly and effectively embedded in government governance, and promote the quality and efficiency of social governance.

In the evolution of the Internet from Web 1.0 to Web 3.0, algorithms have played an irreplaceable role, enabling information technology to functionally realize the transmission of one-way content to decentralized interaction. Algorithms have a subtle impact on people's lives, work, and learning, and this impact is so great that it has produced the idea of algorithmic society and algorithmic era. Algorithms belong to the basic category of digital law and are an important tool for digital rule of law. In existing research, scholars are more concerned about how to regulate algorithms, and less concerned about the legal nature of algorithms. There has been a brief discussion on this issue. However, how the legal nature of algorithms should be defined is still inconclusive. This article aims to answer this question. To this end, this paper sorts out the existing theoretical schemes of the legal nature of algorithms and their interrelationships, including speech, due process, patents, and trade secrets, and analyzes the sources and arguments of these theoretical schemes. There are internal and external reasons why the legal nature of algorithms has formed many disputes. These reasons are also difficult to define the legal nature of algorithms, including: the algorithm ontology and carrier are easy to confuse, the algorithm and the program are indiscriminate, the algorithm and data, the result mix, and the limitation of governance rules. When seeking justification for various theoretical claims, one logical premise is easily overlooked, that is, the criteria for determining the legal nature of algorithms. This paper puts forward these standards, namely the principle of legality, the principle of respecting the fruits of labor, the principle of maintaining public safety, the principle of promoting innovation, and the principle of maximizing social benefits. On this basis, this paper examines various theoretical schemes, and finally proves that the legal nature of the algorithm is a trade secret, not something else. In terms of methodology, this paper uses the method of identification analysis to discuss various scenarios one by one. Compared with previous literature, this paper makes contributions in the following aspects: first, this paper sorts out the existing debates on the legal nature of algorithms in detail, grasps the arguments of these theoretical schemes, and specifically examines them. Second, this paper analyzes the reasons for many disputes over the legal nature of algorithms. The widespread use of algorithms has also caused heated debates about algorithms. Algorithms have been in the field of legal science for a long time, but there are frequent misunderstandings about how their legal nature should be defined, and the reasons behind them deserve careful analysis. Third, this paper clarifies the criteria for defining the legal nature of algorithms, and argues that algorithms are trade secrets on this basis. Algorithms cannot be called speech, nor are they due process. The argument that algorithms are patents is also untenable, and although algorithms have the possibility of patentability in the current legal system, algorithm patenting is not a good solution.

The quality of cocoons directly affects the quality of raw silk. Before reeling, the cocoons should be sorted to remove the inferior cocoons that cannot be used for reeling. The double cocoon is the best raw material for making silk quilts. Therefore, it should be separated from other types of inferior cocoons and classified separately in the process of selecting cocoons. The traditional cocoon sorting basically relies on manpower, which involves high labor intensity, low efficiency of cocoon selection and high missing rate, and the accuracy of cocoon selection is easily affected by subjective factors such as the technical level and mental state of cocoon selection personnel. With the rapid development of artificial intelligence, machine vision technology is widely used to replace human eyes for detection and recognition. At present, in machine vision technology, the recognition of double cocoons mainly includes area threshold method and the threshold method of the ratio of long to short axis of ellipse. The disadvantage of the area threshold method is that small double cocoons cannot be detected. The threshold method of the ratio of long to short axis of ellipse is not applicable to the double cocoon of the head-to-tail type and relies too much on the accurate fitting of the cocoon shape. However, due to the slight irregularity of the cocoon shape, the attachment silk and the adhesion between the cocoons, the ellipse fitting is different from the actual shape, which may result in people’s misjudging the cocoon type near the threshold. Therefore, there are some limitations in the identification of double cocoons by only depending on the area threshold or the threshold of the ratio of long to short axis of the fitted ellipse. Due to the dense distribution of cocoons in the cocoon image and the interference of attached silk, the gray scale of adjacent cocoons is similar, so it is difficult to conduct segmentation completely by traditional image segmentation methods. Therefore, the segmentation and counting problem of target cocoons should be solved first for the classification and recognition of cocoons. Aiming at the problems that it is difficult to accurately segment the adhered cocoons and the limitations of the existing double cocoon recognition methods, we proposed a series of algorithms for the segmentation and counting of cocoons, the shape restoration of cocoons and the recognition of double cocoons. Firstly, we proposed an improved image segmentation algorithm based on variable segmentation threshold by combining with morphological operation. Otsu binarization threshold was used as the initial segmentation threshold, and binarization, morphological erosion operation and morphological expansion operation were performed on the image. The pixel area threshold and length-width threshold of single cocoons were used to distinguish the connected region. If a cocoon is a single one, it is marked and counted. If it is determined to be connected to other cocoons, the segmentation threshold is increased again for another segmentation. Then, a cocoon shape restoration method based on edge detection and ellipse fitting was proposed. The pixels of each cocoon that had been segmented were traversed. The Canny operator was used to detect the edge of the original image. The pixel points of the segmented cocoon were used to determine the edge points of the cocoon, and the edge points were elliptically fitted to obtain the image of the cocoon. Finally, the ratio of long to short axis of the cocoon and the area parameters were calculated, and the double-parameter threshold was used to recognize the double cocoon. And then, the serial algorithm proposed in this paper was used to segment cocoon graphics, restore cocoon shape, and distinguish double cocoons in 10 cocoon images. The results show that the 222 cocoons of all the ten pictures are completely segmented, and the counting accuracy is 100%. A total of 46 double cocoons in the pictures are detected, and the classification accuracy of double cocoons and single cocoons is 98.6%. This method detects the small double cocoons which are easy to be missed by the area threshold method, and accurately identifies the cocoon type which is close to the threshold of the ratio of long to short axis. The series algorithm of cocoon target segmentation and double cocoon recognition proposed in this paper can effectively process the machine vision image to get the conclusion whether each cocoon is a double one. In the series algorithm, the pre-experiment is used to determine the area of the normal cocoon and the length of the long axis of the normal cocoon as the prior conditions in the captured image. The cocoon target with slight overlap can be separated, but the cocoons with serious overlap may be mistakenly divided into the same group, thus affecting the classification and recognition of the cocoon. Therefore, this method is suitable for the image processing of cocoons laid flat in the field of vision. [ABSTRACT FROM AUTHOR]

Droplets deposition characteristics estimation is helpful to know the pesticides deposition distribution on crops, which is related to the crop spray quality directly, and especially the fast detection method will provide the basis for improving the pesticides spraying technology. Droplets image processing based on the water sensitive paper is one of the most common methods to detect the droplets deposition characteristics. The droplets coverage percentage and coverage density were selected to evaluate deposition distribution in this paper. With the development of science and technology, a smart phone was selected as image acquiring tool to replace the special image acquisition system, and the improved image processing algorithm of the water sensitive paper was developed. There are 3 steps in the image processing algorithm to obtain each droplet stain, which are image preprocessing, droplets area segmentation, and overlapped droplets segmentation. Firstly, the image was enhanced and calibrated by a calibration board, and then the image of water sensitive paper was segmented from the R channel and B channel image and transferred to a gray scale image. Secondly, the blue droplets stain area was segmented from yellow paper background, and the dynamic threshold method based on the pixel position was used to solve the problem of the influence of uneven brightness in this step, in which the gray mean value of an area of 25×25 pixels was calculated as the segmentation threshold for the middle pixel, and the droplets coverage percentage was calculated by the stains pixel number divided by the pixel number of water sensitive paper area. Thirdly, the circulatory segmentation method based on region circularity was designed to segment the multiple-droplet overlapped regions. Based on the statistical analysis, 0.6 was selected as the circularity threshold, less than 0.6 was considered to be overlapped droplets, and first erosion and then dilation based on a circle with the radius r were performed; next the segmented area circularity was recalculated, the area with the circularity of greater than 0.6 was selected again and segmented by the circle with the radius (r+1), and the erosion-dilation operation would be repeated over and over until the circularity of all stains was greater than 0.6. Finally, the identified droplets were marked as circle, and the droplets coverage density was calculated by droplets number divided by the water sensitive paper area. Experiments were conducted to test and verify the detection advancement of the proposed image processing algorithm. Experimental results showed that the dynamic threshold segmentation method is not affected by the uneven brightness and can extract 92.64% of droplets, and the droplet coverage percentage detection result is 12.57% and 8.74% greater than constant threshold and partitioned threshold method respectively. Moreover, the proposed overlapped droplets segmentation algorithm can segment successfully more than 2 droplets and the long and thin droplets, the accuracy of droplets identification is 97.2%, and the coverage density detection results showed that the relative error between the algorithm in this paper and manual counting is only 3.31%. The results indicated that the proposed image detection algorithm of droplets deposition characteristics is efficient and convenient, and can completely fulfill the demand of droplets deposition characteristics detection in the field, and the corresponding smartphone applications are in development.

Abstract: Accurate identification of cotton top bud is important for cotton topping operation to detect cotton terminal bud accurately in field, a recognition method using Faster R-CNN (Faster Region Convolutional Neural Networks, Faster R-CNN) by integrating dynamic mechanism was proposed to solve the recognition difficulties caused by the small size of cotton terminal bud when it is topped in densely planted fields. The RegNetX-6.4GF model was used as the backbone network to improve its image feature extractor capabilities. Due to number of proposals under a higher IOU(Intersection Over Union, IOU) as well as the matching degree between anchor and the target shape affect the performance of the detector, the method proposed in this paper changed the original anchor generation mechanism by combining FPN (Feature Pyramid Network, FPN) and Guided Anchoring in RPN (Region Proposal Network, RPN), which will cause the distribution of the proposals generated by the RPN of the algorithm under different IOUs dynamically change during the training process. To adapt the dynamic change of proposals distribution, we integrated Dynamic Region Convolutional Neural Networks ( Dynamic R-CNN) in Faster R-CNN, which can dynamically adjust the value of IOU to obtain high quality proposals. And the GROIE (Generic ROI Extractor, GROIE) mechanism was inducted to extract ROI (Region of Interest, ROI) to improve the feature fusion capability. In this paper, 4 819 images of gossypium hirsutum population which contain seven leaf types were taken from the top of cotton plant at distance of 30-50 cm (medium distance) and 50-100 cm (long distance) under uniform light, oblique strong light, direct strong light, and shadows. Those images were processed as MS COCO 2017 format dataset and assigned to the training set, validation set, and test set, which contained 2 815, 704, and 1 300 pictures respectively. The experimental results demonstrated that FPS (Frames Per Second, FPS) of proposed model was up to 10.3 frames/s and the Mean Average Precision (MAP) of bud identification reached to 98.1% which was 3.2 percentage points higher than original Faster R-CNN model. The validation set were used to compare performance of mainstream recognition algorithm and proposed method. Results showed that the improved Faster R-CNN's MAP was 7.3% higher than original Faster R-CNN, which was also higher than RetinaNet, Cascade R-CNN (Cascade Region Convolutional Neural Networks, Cascade R-CNN) and RepPoints by 78.9%, 10.1% and 8.3% when IOU was set to 0.5. The improved Faster R-CNN proposed in this paper meets the accuracy and real-time requirements of cotton topping operation. [ABSTRACT FROM AUTHOR]
