Shimon Ullman focuses on the processes of high-level vision that deal with the interpretation and use of what is seen in the image. In this book, Shimon Ullman focuses on the processes of high-level vision that deal with the interpretation and use of what is seen in the image. In particular, he examines two major problems. The first, object recognition and classification, involves recognizing objects despite large variations in appearance caused by changes in viewing position, illumination, occlusion, and object shape. The second, visual cognition, involves the extraction of shape properties and spatial relations in the course of performing visual tasks such as object manipulation, planning movements in the environment, or interpreting graphical material such as diagrams, graphs and maps. The book first takes up object recognition and develops a novel approach to the recognition of three-dimensional objects. It then studies a number of related issues in high-level vision, including object classification, scene segmentation, and visual cognition. Using computational considerations discussed throughout the book, along with psychophysical and biological data, the final chapter proposes a model for the general flow of information in the visual cortex. Understanding vision is a key problem in the brain sciences, human cognition, and artificial intelligence. Because of the interdisciplinary nature of the theories developed in this work, High-Level Vision will be of interest to readers in all three of these fields.

The Lord's Resistance Army is Africa's most persistent and notorious 'terrorist' group. Led by the mysterious Joseph Kony, it has committed a series of horrific human rights abuses, including massacres and mutilations. Since the mid 1980s, it has abducted tens of thousands of people, including large numbers of children forced to train as fighters. The IC in 2005 issued warrants for Kony and his top commanders, and the United States is backing a military campaign against the group. But the LRA survives, continuing to inspire both fascination and fear. Authoritative but provocative, The Lord's Resistance Army provides the most comprehensive analysis of the group available. From the roots of the violence to the oppressive responses of the Ugandan government and the failures of the international community, this collection looks at this most brutal of conflicts in fascinating depth, and includes a remarkable first-hand interview with Kony himself.

Many approaches have been proposed to solve the problem of finding the optic flow field of an image sequence. Three major classes of optic flow computation techniques can discriminated (see for a good overview Beauchemin and Barron IBeauchemin19951): gradient based (or differential) methods; phase based (or frequency domain) methods; correlation based (or area) methods; feature point (or sparse data) tracking methods; In this chapter we compute the optic flow as a dense optic flow field with a multi scale differential method. The method, originally proposed by Florack and Nielsen [Florack1998a] is known as the Multiscale Optic Flow Constrain Equation (MOFCE). This is a scale space version of the well known computer vision implementation of the optic flow constraint equation, as originally proposed by Horn and Schunck [Horn1981]. This scale space variation, as usual, consists of the introduction of the aperture of the observation in the process. The application to stereo has been described by Maas et al. [Maas 1995a, Maas 1996a]. Of course, difficulties arise when structure emerges or disappears, such as with occlusion, cloud formation etc. Then knowledge is needed about the processes and objects involved. In this chapter we focus on the scale space approach to the local measurement of optic flow, as we may expect the visual front end to do. 17. 2 Motion detection with pairs of receptive fields As a biologically motivated start, we begin with discussing some neurophysiological findings in the visual system with respect to motion detection.

Romance and action come crashing together in Susan Adrian's Tunnel Vision in which a teenage boy with incredible powers is brought to the attention of the government. Jake Lukin just turned 18. He's decent at tennis and Halo, and waiting to hear on his app to Stanford. But he's also being followed by a creep with a gun, and there's a DARPA agent waiting in his bedroom. His secret is blown. When Jake holds a personal object, like a pet rock or a ring, he has the ability to "tunnel" into the owner. He can sense where they are, like a human GPS, and can see, hear, and feel what they do. It's an ability the government would do anything to possess: a perfect surveillance unit who could locate fugitives, spies, or terrorists with a single touch. Jake promised his dad he'd never tell anyone about his ability. But his dad died two years ago, and Jake slipped. If he doesn't agree to help the government, his mother and sister may be in danger. Suddenly he's juggling high school, tennis tryouts, flirting with Rachel Watkins, and work as a government asset, complete with 24-hour bodyguards. Forced to lie to his friends and family, and then to choose whether to give up everything for their safety, Jake hopes the good he's doing—finding kidnap victims and hostages, and tracking down terrorists—is worth it. But he starts to suspect the good guys may not be so good after all. With Rachel's help, Jake has to try to escape both good guys and bad guys and find a way to live his own life instead of tunneling through others.

In its early years, the field of computer vision was largely motivated by researchers seeking computational models of biological vision and solutions to practical problems in manufacturing, defense, and medicine. For the past two decades or so, there has been an increasing interest in computer vision as an input modality in the context of human-computer interaction. Such vision-based interaction can endow interactive systems with visual capabilities similar to those important to human-human interaction, in order to perceive non-verbal cues and incorporate this information in applications such as interactive gaming, visualization, art installations, intelligent agent interaction, and various kinds of command and control tasks. Enabling this kind of rich, visual and multimodal interaction requires interactive-time solutions to problems such as detecting and recognizing faces and facial expressions, determining a person's direction of gaze and focus of attention, tracking movement of the body, and recognizing various kinds of gestures. In building technologies for vision-based interaction, there are choices to be made as to the range of possible sensors employed (e.g., single camera, stereo rig, depth camera), the precision and granularity of the desired outputs, the mobility of the solution, usability issues, etc. Practical considerations dictate that there is not a one-size-fits-all solution to the variety of interaction scenarios; however, there are principles and methodological approaches common to a wide range of problems in the domain. While new sensors such as the Microsoft Kinect are having a major influence on the research and practice of vision-based interaction in various settings, they are just a starting point for continued progress in the area. In this book, we discuss the landscape of history, opportunities, and challenges in this area of vision-based interaction; we review the state-of-the-art and seminal works in detecting and recognizing the human body and its components; we explore both static and dynamic approaches to "looking at people" vision problems; and we place the computer vision work in the context of other modalities and multimodal applications. Readers should gain a thorough understanding of current and future possibilities of computer vision technologies in the context of human-computer interaction.
