Biological and machine systems exist within a complex and changing three-dimensional world. We appear to have no difficulty understanding this world, but how do we go about forming a perceptual model of it? Centred around three key themes: depth processing and stereopsis; motion and navigation in 3D; and natural scene perception, this volume explores the latest cutting-edge research into the perception of three dimension environments. It features contributions from top researchers in the field, presenting both biological and computational perspectives. Topics covered include binocular perception; blur and perceived depth; stereoscopic motion in depth; and perceiving and remembering the shape of visual space. This unique book will provide students and researchers with an overview of ongoing research as well as perspectives on future developments in the field. Colour versions of a selection of the figures are available at www.cambridge.org/9781107001756.

This book introduces the geometry of 3-D vision, that is, the reconstruction of 3-D models of objects from a collection of 2-D images. It details the classic theory of two view geometry and shows that a more proper tool for studying the geometry of multiple views is the so-called rank consideration of the multiple view matrix. It also develops practical reconstruction algorithms and discusses possible extensions of the theory.

This monograph by one of the world's leading vision researchers provides a thorough, mathematically rigorous exposition of a broad and vital area in computer vision: the problems and techniques related to three-dimensional (stereo) vision and motion. The emphasis is on using geometry to solve problems in stereo and motion, with examples from navigation and object recognition. Faugeras takes up such important problems in computer vision as projective geometry, camera calibration, edge detection, stereo vision (with many examples on real images), different kinds of representations and transformations (especially 3-D rotations), uncertainty and methods of addressing it, and object representation and recognition. His theoretical account is illustrated with the results of actual working programs.Three-Dimensional Computer Vision proposes solutions to problems arising from a specific robotics scenario in which a system must perceive and act. Moving about an unknown environment, the system has to avoid static and mobile obstacles, build models of objects and places in order to be able to recognize and locate them, and characterize its own motion and that of moving objects, by providing descriptions of the corresponding three-dimensional motions. The ideas generated, however, can be used indifferent settings, resulting in a general book on computer vision that reveals the fascinating relationship of three-dimensional geometry and the imaging process.

Humans appear to solve complex vision tasks in an almost effortless manner, as compared to their computer counterparts. One major reason for this is the intelligent cooperation between the sensory and the motor system, which is facilitated by development of motor skills that help to shape visual information that is relevant to a specific vision task. This dynamic interaction of sensory-motor components in biological systems can be a great inspiration to how artificial systems, such as robots could use their visual mechanism to interacts with their world. In this thesis, we seek to explore an approach to active visioninspired by biological evolution, which does not use a predefined framework or assumptions, but develops motor strategies for a given task through progressive adaptation of the evolutionary method. Thus, this kind of approach will give freedom to artificial systems in the discovery of eye movement strategies that may be useful to biological systems but are not known to us. The contributions of this thesis are: 1. We used this type of active vision system for more complex images taken from the camera of the iCub robot.2. We demonstrated the effectiveness of the active vision system in a more realistic setting for 3D object categorisation using the humanoid robot (iCub) platform.3. We extended the applicability of the system to the 3D environment for indoor and outdoor environment classification task using the iCub platform.4. We extended the system with pre-processing using Uniform Local Binary Patterns [1] in both 2D and 3D environment categorisation tasks.5. We further extended the system with pre-processing using Histogram of Oriented Gradients [2] for classification tasks in the 2D and 3D environments.Analysis of the results from the system shows that the model was able to complete discrimination tasks through: (i) exploiting sensory-motor coordination to experience sensory stimuli that facilitates the classification tasks; (ii) an indication of integration of perceptual information over time.

Computational models of human cognition have been applied to many complex real-world tasks including air traffic control, human-computer interaction, learning arithmetic, traversing the World Wide Web, intelligent tutors, instrument-based flight, and vehicle driving. There are numerous additional applications for these computational models including integration with models of human motion, military simulation of enemy agents in virtual environment training, testing of new vehicle designs or machine interfaces, and analysis of cognitive components of tasks. However, most of these models exist in limited two-dimensional (2D) environments. In order to apply computational models to tasks in a dynamic three-dimensional world, extensions to current cognitive architectures must provide the capability for models to perceive, process, and act in the threedimensional environments. The current research will seek to extend the vision components of a cognitive architecture to support computational models capable of simulating human vision in a dynamic three-dimensional (3D) environment.
