Cayce Pollard, a design consultant, is on the trail of the creator of Internet videos that have attained a worldwide cult following. As she draws closer to the truth, Cayce's life is threatened by those who will stop at nothing to protect the secret of the videos.
The motivation of this work was to introduce all-optical holographic techniques to
complement other optoelectronic techniques in a nonlinear correlator. These
correlators are improved by replacing the various serial computational algorithms
in the Fourier plane (used in optoelectronic correlators3-10) with an optically
addressed nonlinear device. The first implementation of the nonlinear
optoelectronic joint transform correlator (JTC) used binarization of the joint power
spectrum with a ...
Hand Posture and Face Recognition using Biologically Inspired Approaches
This book presents a collection of computational intelligence algorithms that addresses issues in visual pattern recognition such as high computational complexity, abundance of pattern features, sensitivity to size and shape variations and poor performance against complex backgrounds. The book has 3 parts. Part 1 describes various research issues in the field with a survey of the related literature. Part 2 presents computational intelligence based algorithms for feature selection and classification. The algorithms are discriminative and fast. The main application area considered is hand posture recognition. The book also discusses utility of these algorithms in other visual as well as non-visual pattern recognition tasks including face recognition, general object recognition and cancer / tumor classification. Part 3 presents biologically inspired algorithms for feature extraction. The visual cortex model based features discussed have invariance with respect to appearance and size of the hand, and provide good inter class discrimination. A Bayesian model of visual attention is described which is effective in handling complex background problem in hand posture recognition. The book provides qualitative and quantitative performance comparisons for the algorithms outlined, with other standard methods in machine learning and computer vision. The book is self-contained with several figures, charts, tables and equations helping the reader to understand the material presented without instruction.
