The development of behavior modification principles and procedures and the ensuing research have had a dramatic impact on services for mentally re tarded persons. This book is the second edition of a volume that is designed to update readers on some of these many developments. Although many of the chapter titles and authors from the first edition remain unchanged, we have added additional chapters to reflect new areas of research. The book is thus a critical review of this literature and, as such, provides essential and important notions about what we know and what can be done to expand our...

In this groundbreaking new volume, computer researchers discuss the development of technologies and specific systems that can interpret data with respect to domain knowledge. Although the chapters each illuminate different aspects of image interpretation, all utilize a common approach - one that asserts such interpretation must involve perceptual learning in terms of automated knowledge acquisition and application, as well as feedback and consistency checks between encoding, feature extraction, and the known knowledge structures in a given application domain. The text is profusely illustrated...

This comprehensive reference introduces the intricate science of implementing image modelling and retrieval based on the shape, on the colour and texture, or on spatial arrangement of imaged objects.

With the recent advances in multimedia technology, on-line libraries of digital images are assuming an ever increasing relevance within a wide range of information systems. Effective access to such archives requires on external textual keywords that conventional searching techniques based are complemented by content-based queries addressing appearing visual features of searched data. Central to this retrieval approach is the creation of models, which permit to abstract images into some space of features and support indexing and comparison of visual contents. Depending on the specific...

Irrespective of the necessities described above, and with the excep tion of specific generic application systems (e.g., bare-board PCB inspection, wafer inspection, solder joint inspection, linewidth measure ment), vision systems are still not found...

Computer vision deals with the problem of manipulating information contained in large quantities of sensory data, where raw data emerge from the transducing 6 7 sensors at rates between 10 to 10 pixels per second. Conventional general- purpose computers are unable to achieve the computation rates required to op- erate in real time or even in near real time, so massively parallel systems have been used since their conception in this important practical application area. The development of massively parallel computers was initially character- ized by efforts to reach a speedup factor equal to...

It has long been a dream to realize machines with flexible visual perception capability. Research on digital image processing by computers was initiated about 30 years ago, and since then a wide variety of image processing algorithms have been devised. Using such image processing algorithms and advanced hardware technologies, many practical ma- chines with visual recognition capability have been implemented and are used in various fields: optical character readers and design chart readers in offices, position-sensing and inspection systems in factories, computer tomography and medical X-ray...

This book gathers together information concerning the interaction of hu- man stereopsis with various stereoscopic viewing devices, especially those used in teleoperator systems. The book is not concerned with machine vi- sion systems. In these systems, data analogous to human binocular visual information is gathered and analyzed by some device for use in decision making or control, often without the intervention of a human. This subject presents problems of considerable complexity; it has generated many inge- nious solutions and has been the inspiration of much work of fundamental importance....
