沖縄本島南部地域の湧水の特性と周辺環境を基に類型化を試みるとともに, 湧水に対する住民の意識・行動を調査・分析した。結果は以下の通りである。湧水は, 自然, 社会, 生産, レクリエーションといった多面的な機能を備えており, すぐれた地域資源といえる。湧水の利活用を考えるとき, 湧水の個々の特徴が発揮されるような整備計画とすることが重要である。湧水は自然型, 集落型, 農地型, 公園型の4つに類型化できた。自然型の特性は, 湧水の形態が自然に近い状態にあり, 湧水周辺の自然環境が豊かである。集落型は村落と密接に関わっており管理が行き届いている。農地型は, 農地内にあって, 農業用水としても十分利用され, 湧水の周辺に小規模ながら自然が残されている。公園型は, 湧水を利用した公園として整備され, 都市近郊農村などの住宅が多い所では手軽に水と触れ合える場所になっている。湧水に訪れる人は徒歩によるものがほとんどであり, その利用頻度は集落型で高く, 自然型で低かった。湧水と住宅との距離が利用頻度を左右しており, 利用頻度の高い湧水に対して親近感をもつ人が多いようである。利用内容は自然型, 集落型, 公園型で散歩や拝みが多く, 農地型では農業用水としての利用が最も多い。農地型では湧水が生産手段の一部として認識されているのに対して, 集落型や公園型では生活環境やレクリエーション空間の一部であるという認識が強い。, Evaluation and utilization of springs-wells in the southern part of Okinawa Island were considered, and following results were obtained. Springs-wells may be divided into four types based on our study, namely, natural type, settlement-type, farmland-type and park-type. The human perception concerning the spring-well differs in its pattern and feature. For the springs-wells of natural type, it is expected to install a walk for visitors in maintenance of preservation of the natural environment. For the springs-wells of settlement-type, the utilization as a place of recreation and relaxation and the daily water-use are expected. For the springs-wells of farmland-type, the utilization as agricultural water and a place of recreation and relaxation are considered. For the springs-wells of park-type, the good or bad condition of maintenance of the water amenity facilities governs the evaluation and the utilization of these improvement projects. We need to recognize the historical and cultural value of springs-wells, and such the valuable springs-wells should be utilized as a place of study. Springs-wells are waterside spots, which have natural, social, productive and recreational functions, and it is not too much to say that they are superior regional resources., 紀要論文

- Abstract
This is the final report for the Air Force Office of Scientific Research grant entitled 'A Study of Texture Analysis Algorithms'. As such this report attempts to provide an overview of the research that was performed and to provide a chronology of the events which precipitated the various studies conducted. The research described ranges from developing a theoretical comparison method for evaluating the innate abilities of texture analysis algorithms to a formal mathematical method for defining texture measures. The desire was to develop improved texture analysis methods through a systematic theoretical development process. the goal was to create a texture analysis algorithm which could match a level of human perception. The studies described include a comparison of some texture analysis algorithms, the development of a structural texture analyzer based on statistical methods, the examination of texture pairs which are counter examples to the Julesz conjecture, the development of an image segmentation method based on texture analysis methods, the development of a target recognition strategy based on texture methods, and finally a formal mathematical procedure for defining texture measures.

- Abstract
Recent attacks on airports exposed an emerging threat to the security of the traveling public, attacks on soft targets. Incidents throughout the world indicate that terrorists, seeking to maximize life loss, and economic and symbolic destruction, have changed their focus to soft targets. The thesis examines plausible deterrence measures through environmental design for crowd protection in the aviation transportation sector. The policies of the United Kingdom, Belgium, and the United States Department of Homeland Security, Transportation Security Administration (TSA), are compared to extract best practices for soft target security. Using case analysis of terror attacks on airports in Brussels (2016), Los Angeles (2013), and Glasgow (2007), operational space, deterrence, infrastructure design, and human perception are explored as a means to reduce risk. The thesis finds that new airport environmental design strategies are required to protect crowds, harden the infrastructure, and build resilient structures. The thesis recommends applying environmental design countermeasures in the typically crowded areas of airline ticketing queues, TSA passenger security checkpoints, and baggage areas by changing the adversaries’ perception of opportunistic targets. New risk-assessment models, changes to physical structures, use of new technology including robotics, and the broader use of simulation models are identified as required paths to improve the effective security of soft targets in airports., http://archive.org/details/softtargetsecuri1094558317, Human Resources Specialist and Management Control Program Manager, Transportation Security Administration, Dallas/Fort Worth International Airport, Approved for public release; distribution is unlimited.

- Abstract
Noise concerns frequently pose a barrier to widespread implementation of wind turbines and while the perception of noise from large turbines has been investigated, there is a relative gap in the research for small and micro wind turbines. This paper presents findings from interdisciplinary research linking noise measurements from small wind installations with an investigation into the effect of individual personality traits and noise perception. A survey distributed to households living close to one of 12 micro or small turbine sites, coupled with environmental noise measurements was analysed. The survey showed that the most commonly perceived noises are ‘swooshing’ and ‘humming’, the presence of which may be inferred from the measured frequency spectra. Exploration of survey results showed individuals with a more negative attitude to wind turbines perceive more noise from a turbine located close to their dwelling and those perceiving more noise report increased levels of general symptoms. Individuals' personality also affected attitudes to wind turbines, noise perception from small and micro turbines and symptom reporting.

Humans’ proneness to see faces even in inanimate structures such as cars has long been noticed, yet empirical evidence is scarce. To examine this tendency of anthropomorphism, participants were asked to compare specific features (such as the eyes) of a face and a car front presented next to each other. Eye movement patterns indicated on which visual information participants relied to solve the task and clearly revealed the perception of facial features in cars, such as headlights as eyes or grille as nose. Most importantly, a predominance of headlights was found in attracting and guiding people’s gaze irrespective of the feature they were asked to compare – equivalent to the role of the eyes during face perception. This response to abstract configurations is interpreted as an adaptive bias of the respective inherent mechanism for face perception and is evolutionarily reasonable with regard to a »better safe than sorry« strategy.

In nature, textures can be found everywhere. Texture, together with color and shape, represents the fundamental characteristics of objects. Texture conveys an idea of repetition of a certain structure, which is not limited only to the visual domain. We can refer to the texture of a sound, a fabric, or a certain wine. In image processing, a static texture is defined as an image showing spatial stationarity, while a dynamic texture is a sequence of images showing temporal stationarity. Texture synthesis is the process of producing artificial textures starting from a given texture sample. In this thesis, we consider texture synthesis starting from compact representations. For static, this reduces to define the smallest portion of a texture that, when used for synthesis, produces a synthetic texture indistinguishable from the original image. We designed a psychophysical experiment to quantify this size for a collection of textures and two synthesis algorithms: the parametric algorithm by Portilla and Simoncelli and the procedural algorithm by Nealen and Alexa. The results of the experiment show that for pre-attentive vision condition the size of the compact texture does not depend on the algorithm used for synthesis but is a characteristic of the texture. We evaluated if an objective function, based on spatial correlation between pixels, is able to predict the texture size necessary for synthesis. We found that a statistical measure based on random walks correlated well with the results of the subjective experiment. In the case of dynamic textures, the term "compact" applies to the model size that is used for synthesis. We propose a dynamic texture analysis that is able to obtain a more compact model starting from the linear model of Soatto and Doretto. Current methods perform a dimension reduction of the data by applying the SVD to the video frames unfolded into column vectors. This permits only to exploit the temporal correlation. We avoid the unfolding operations and decompose the signal directly using a multidimensional decomposition known as Higher-Order SVD (HOSVD). Chromatic components are exploited more efficiently by combining the HOSVD decomposition with the YCbCr color encoding for the input data. Tests show that the combined model has far fewer parameters than models derived with other algorithms, for the same visual quality and approximately the same computational synthesis cost. The HOSVD-based model was used in two applications for portable devices where memory and computational power are limited. We created a video effect for webcams and smartphones where a dynamic texture is synthesized and blended to the video in real time.

International audience; The creation of high quality panoramic videos for immersive VR content is commonly done using a rig with multiple cameras covering the required scene. Unfortunately, this setup introduces both spatial and temporal artifacts due to the difference in optical centers as well as imperfect synchronization of cameras. Traditional image quality metrics are inadequate for describing geometric distortions in panoramic videos. In this paper, we propose an objective quality assessment approach for calculating these distortions based on optical flow coupled with an existing salience detection model. Our approach is validated with a human-centered study using error annotations and eye-tracking. Preliminary results indicate a good correlation between errors detected by the algorithm and human perception of errors.

We summarize recent modeling studies of injection-induced fault reactivation, seismicity, and its potential impact on surface structures and nuisance to the local human population. We used coupled multiphase fluid flow and geomechanical numerical modeling, dynamic wave propagation modeling, seismology theories, and empirical vibration criteria from mining and construction industries. We first simulated injection-induced fault reactivation, including dynamic fault slip, seismic source, wave propagation, and ground vibrations. From co-seismic average shear displacement and rupture area, we determined the moment magnitude to about Mw = 3 for an injection-induced fault reactivation at a depth of about 1000 m. We then analyzed the ground vibration results in terms of peak ground acceleration (PGA), peak ground velocity (PGV), and frequency content, with comparison to the U.S. Bureau of Mines’ vibration criteria for cosmetic damage to buildings, as well as human-perception vibration limits. For the considered synthetic Mw = 3 event, our analysis showed that the short duration, high frequency ground motion may not cause any significant damage to surface structures, and would not cause, in this particular case, upward CO2 leakage, but would certainly be felt by the local population., Energy Procedia, 63, ISSN:1876-6102, 12th International Conference on Greenhouse Gas Control Technologies, GHGT-12

Building occupants are continuously exposed to multiple indoor environmental stimuli, including thermal, visual, acoustic, and air quality related factors. Moreover, personal and contextual aspects can be regarded as additional domains influencing occupants' perception and behaviour. The scientific literature in this area typically deals with these multiple stimuli in isolation. In contrast to single-domain research, multi-domain research analyses at least two different domains, for example, visual and thermal. The relatively few literature reviews that have considered multi-domain approaches to indoor-environmental perception and behaviour covered only a few dozen articles each. The present contribution addresses this paucity by reviewing 219 scientific papers on interactions and cross-domain effects that influence occupants' indoor environmental perception and behaviour. The objective of the present review is to highlight motivational backgrounds, key methodologies, and major findings of multi-domain investigations of human perception and behaviour in indoor environments. The in-depth review of these papers provides not only an overview of the state of the art, but also contributes to the identification of existing knowledge gaps in this area and the corresponding need for future research. In particular, many studies use "convenience" variables and samples, there is often a lack of theoretical foundation to studies, and there is little research linking perception to action.

The present paper brings together solutions for full-automatic analysis of chess moves and eye tracking data for real dyadic chess games. We combine an electronic chessboard with marker detection in order to automatically protocol relevant and situation-related chess moves and visual attention patterns on pieces and squares. Very first results from initial evaluation studies indicate that the presented solution allows for a reliable automatic offline analysis of the underlying strategic and attentional processes of chess behaviour in real game situations without any need for an error prone and time consuming manual data annotation. The proposed solution allows to run chess studies in shorter time and to analyse the differences between chess experts and novices with respect to visual attention and strategies in more detail. Finally, gained insights can be used to develop interactive and intuitive electronic chess assistant systems to analyse the weaknesses of both experts and novices and to recommend optimal moves in given chess situations, as well as to enhance players’ expertise with individualized training methods and explanations., HAL Id: hal-01617691

Texture is extensively used in areas such as product design and architecture to convey specific aesthetic information. Using the results of a psychological experiment, we model the relationship between computational texture features and aesthetic properties of visual textures. Contrary to previous approaches, we build a layered model, which provides insights into hierarchical relationships involved in human aesthetic texture perception. This model uses a set of intermediate judgements to link computational texture features with aesthetic texture properties. We pursue two different approaches for modeling. (1) Supervised machine-learning methods are used to generate linear and nonlinear models from the experimental data automatically. The quality of these models is discussed, mainly focusing on interpretability and accuracy. (2) We apply a psychological-based approach that models the processing pathways in human perception of naturalness, introducing judgement dimensions (principal components) mediating the relationship between texture features and naturalness judgements. This multiple mediator model serves as a verification of the machine-learning approach. We conclude with a comparison of these two approaches, highlighting the similarities and discrepancies in terms of identified relationships between computational texture features and aesthetic properties of visual textures.

This paper describes the development of three main functionalities for a domestic mobile service robot and an automatic benchmarking system used for the systematic performance evaluation of the robot’s functionalities. Three main robot functionalities are addressed: (1) People Perception, (2) People Following and (3) Pick and Placing, where the hardware and software systems developed for each functionality are described and demonstrated on an actual mobile service robot, with the goal of providing assistance to an elderly person inside the house. Furthermore, a set of innovative benchmarks and an automatic performance evaluation system are proposed and used to evaluate the performance of the developed functionalities. These benchmarks are now made publicly available and is part of the European Robotics League (ERL)-Consumer to systematically evaluate the performance of service robot solutions at different testbeds around Europe.
