Book Description
In this chapter we describe the main problems associated with the integration of active vision and multitasking. This configuration, though attractive, must be properly handled by means of simplification strategies that cope with its inherent complexity. Besides, the programming of this kind of complex system is prone to conclude often in monolithic adhoc solutions. These problems are illustrated through the analysis of MTVS, a prototype system that proposes an open architecture for the integration of concurrent visual tasks. In MTVS the client's requests are articulated on the basis of a reduced set of services or visual primitives. All the low level control/coordination aspects are hidden to the clients simplifying the programming and allowing for an open and dynamic composition of visual activity from much simpler visual capabilities. Regarding the gaze control assignation problem, several schedulers have been implemented. The best results are obtained by a contextual scheme governed by urgencies, taking the interaction of the agent with its environment as organization principle instead of temporal frequencies. Usually, a correspondence between urgency and uncertainty about a relevant task element can be established. The internal structure of MTVS, its organization in terms of visual primitives and its separated scheduling mechanisms contribute to obtain modular software applications that facilitate maintenance and promote software reuse.

Book Description
This unique book explores the important issues in studying for active visual perception. The book’s eleven chapters draw on recent important work in robot vision over ten years, particularly in the use of new concepts. Implementation examples are provided with theoretical methods for testing in a real robot system. With these optimal sensor planning strategies, this book will give the robot vision system the adaptability needed in many practical applications.

Book Description
The purpose of robot vision is to enable robots to perceive the external world in order to perform a large range of tasks such as navigation, visual servoing for object tracking and manipulation, object recognition and categorization, surveillance, and higher-level decision-making. Among different perceptual modalities, vision is arguably the most important one. It is therefore an essential building block of a cognitive robot. This book presents a snapshot of the wide variety of work in robot vision that is currently going on in different parts of the world.

Book Description
In this paper, an active vision system is developed which is based on image strategy. The image based control structure uses the optical flow algorithm for motion detection of an object in a visual scene. Because the optical flow is very sensitive to changes in illumination or to the quality of the video, it was necessary to use median filtering and erosion and dilatation morphological operations for the decrease of erroneous blobs residing in individual frames. Since the image coordinates of the object are subjected to noise, the Kalman filtering technique is adopted for robust estimation. A fuzzy controller based on the fuzzy condensed algorithm allows real time work for each captured frame. Finally, the proposed active vision system has been simulated in the development/simulation environment Matlab/Simulink.

Book Description
Visual perception is one of the most important sources of information for both humans and robots. A particular challenge is the acquisition and interpretation of complex unstructured scenes. This work contributes to active vision for humanoid robots. A semantic model of the scene is created, which is extended by successively changing the robot's view in order to explore interaction possibilities of the scene.

Book Description
The book constitutes the refereed proceedings of the International Workshop on Algebraic Frames for the Perception-Action Cycle, AFPAC '97, held in Kiel, Germany, in September 1997. The volume presents 12 revised full papers carefully reviewed and selected for inclusion in the book. Also included are 10 full invited papers by leading researchers in the area providing a representative state-of-the-art assessment of this rapidly growing field. The papers are organized in topical sections on PAC systems, low level and early vision, recognition of visual structure, processing of 3D visual space, representation and shape perception, inference and action, and visual and motor neurocomputation.
