Human-Centric Machine Vision

Recently, the algorithms for the processing of the visual information have greatly evolved, providing efficient and effective solutions to cope with the variability and the complexity of real-world environments. These achievements yield to the development of Machine Vision systems that overcome the typical industrial applications, where the environments are controlled and the tasks are very specific, towards the use of innovative solutions to face with everyday needs of people. The Human-Centric Machine Vision can help to solve the problems raised by the needs of our society, e.g. security and safety, health care, medical imaging, and human machine interface. In such applications it is necessary to handle changing, unpredictable and complex situations, and to take care of the presence of humans

Emotion Recognition for Affective Computing: Computer Vision and Machine Learning Approach

The purpose of affective computing is to develop reliable and intelligent models that computers can use to interact more naturally with humans. The critical requirements for such models are that they enable computers to recognise, understand and interpret the emotional states expressed by humans. The emotion recognition has been a research topic of interest for decades, not only in relation to developments in the affective computing field but also due to its other potential applications. A particularly challenging problem that has emerged from this body of work, however, is the task of recognising facial expressions and emotions from still images or videos in real-time. This thesis aimed to solve this challenging problem by developing new techniques involving computer vision, machine learning and different levels of information fusion. Firstly, an efficient and effective algorithm was developed to improve the performance of the Viola-Jones algorithm. The proposed method achieved significantly higher detection accuracy (95%) than the standard Viola-Jones method (90%) in face detection from thermal images, while also doubling the detection speed. Secondly, an automatic subsystem for detecting eyeglasses, Shallow-GlassNet, was proposed to address the facial occlusion problem by designing a shallow convolutional neural network capable of detecting eyeglasses rapidly and accurately. Thirdly, a novel neural network model for decision fusion was proposed in order to make use of multiple classifier systems, which can increase the classification accuracy by up to 10%. Finally, a high-speed approach to emotion recognition from videos, called One-Shot Only (OSO), was developed based on a novel spatio-temporal data fusion method for representing video frames. The OSO method tackled video classification as a single image classification problem, which not only made it extremely fast but also reduced the overfitting problem

Conference on Intelligent Robotics in Field, Factory, Service, and Space (CIRFFSS 1994), volume 1

The AIAA/NASA Conference on Intelligent Robotics in Field, Factory, Service, and Space (CIRFFSS '94) was originally proposed because of the strong belief that America's problems of global economic competitiveness and job creation and preservation can partly be solved by the use of intelligent robotics, which are also required for human space exploration missions. Individual sessions addressed nuclear industry, agile manufacturing, security/building monitoring, on-orbit applications, vision and sensing technologies, situated control and low-level control, robotic systems architecture, environmental restoration and waste management, robotic remanufacturing, and healthcare applications

Second Aerospace Environmental Technology Conference

The mandated elimination of CFC'S, Halons, TCA, and other ozone depleting chemicals and specific hazardous materials has required changes and new developments in aerospace materials and processes. The aerospace industry has been involved for several years in providing product substitutions, redesigning entire production processes, and developing new materials that minimize or eliminate damage to the environment. These activities emphasize replacement cleaning solvents and their application, verification, compliant coatings including corrosion protection system and removal techniques, chemical propulsion effects on the environment, and the initiation of modifications to relevant processing and manufacturing specifications and standards
