8. Exploring the Potentials of Crowdsourcing for Gesture Data Collection.

Abstract

Gesture data collection in a controlled lab environment often restricts participants to performing gestures in a uniform or biased manner, resulting in gesture data which may not sufficiently reflect gesture variability to build robust gesture recognition models. Crowdsourcing has been widely accepted as an efficient high-sample-size method for collecting more representative and variable data. In this study, we evaluated the effectiveness of crowdsourcing for gesture data collection, specifically for gesture variability. When compared to a controlled lab environment, crowdsourcing resulted in improved recognition performance of 8.98% and increased variability for various gesture features, eg, a 142% variation increase for Quantity of Movement. Integrating a supplemental gesture data collection methodology known as Styling Words increased recognition performance by an additional 2.94%. The study also investigated the efficacy of gesture collection methodologies and gesture memorization paradigms. [ABSTRACT FROM AUTHOR]

Abstract

Morphological information on fine particles is essential for understanding their transport behavior in the ambient atmosphere and in the human respiratory system. More than 3000 transmission electron microscopy (TEM) images of fine particles were collected from ambient atmosphere and directly from various sources, such as diesel and gasoline engine exhaust, biomass burning, coal combustion, and road dust, and were then morphologically categorized into four major classes (spherical, agglomerate, polygonal, and dendrite). Pre-trained convolutional neural network (CNN) models (DenseNet169, InceptionV3, MobileNetV3Small, ResNet50, and VGG16) and traditional machine learning models (decision trees, random forests, and support vector machines) were trained using the classified particles. The fine-tuned CNN model (DenseNet169) having the deepest feature learning exhibited the best performance among the tested models, with an overall classification accuracy of 89% and an average per-class accuracy ranging from 84% to 97%. The reliable classification of thousands of images was performed within several minutes. The agglomerated class was the least misclassified because of its significantly different features from those of the other classes. The critical regions of the particles for classification decisions varied among the pre-trained models. Our results suggest that the pre-trained CNN models would be useful for the rapid morphological classification of a large number of fine particles.

11. Image-Based Inspection Technique of a Machined Metal Surface for an Unmanned Lapping Process

Author

Ravimal, Dinuka, Kim, Hanul, Koh, Daegwon, Hong, Jin Hyuk, and Lee, Sun-Kyu

Abstract

This paper presents a new machine vision framework for the efficient examination and classification of surface textures on medium- and large-sized mold products, such as used for automobiles, TVs, and refrigerators. Existing techniques, which are based on the hands and eyes of skilled workers, are inconsistent and time-consuming. Although there are many types of precise surface inspection and measurement methods, most are difficult to apply at industrial sites or by finishing robots due to problems such as speed, setup limitations, and robustness. This paper proposes two techniques based on image processing that aims to automate surface inspection during an unmanned lapping process that is mainly employed to eliminate milling tool marks. First, both the shape of the reflected light and the intensity of the captured near-field contrast image right after the reflected specular are used to determine the machined surface state, and the presence of tool marks as the line light source scans counter-clockwise. Second, the photometric stereo technique is used to detect surface scratches through the normal map that recovers the surface. The proposed techniques show localized machined patterns and classify them with high accuracy.
