Image Recognition and Classification Algorithms, Systems, and Applications
Human visual performance greatly exceeds computer capabilities, probably because of superior high-level image understanding, contextual knowledge, and massively parallel processing. Human capabilities deteriorate drastically in a low-visibility environment or after an extended period of surveillance, and certain working environments are either inaccessible or too hazardous for human beings. For these reasons, automatic recognition systems are...

Handbook of Wireless Networks and Mobile Computing
The past five decades have witnessed startling advances in computing and communication technologies that were stimulated by the availability of faster, more reliable, and cheaper electronic components. The design of smaller and more powerful devices enabled their mobility, which is rapidly changing the way we compute and communicate. For instance, the worldwide number of cellular phone subscribers has quadrupled in the last five years and has...

Fundamentals of wavelets theory algorithms and applications
Most existing books on wavelets are either too mathematical or they focus on too narrow a specialty. This book provides a thorough treatment of the subject from an engineering point of view. It is a one-stop source of theory, algorithms, applications, and computer codes related to wavelets.

Electronics for hobbyists - Digital computers
Digital circuits were originally developed to provide a means of implementing digital computers. As new circuits and techniques were developed, computer performance was improved. But the greatest impact on digital computers has been the development of integrated circuits, or "IC's," which made them more powerful and greatly reduced their size and cost.

In this chapter, we adopt user-defined salient image features as training examples for a specially designed model-based neural network to perform feature detection. Specifically, we have investigated an alternative MBNN with hierarchical architecture [48, 62, 128] which is capable of learning user-specified features through an interactive process. It will be shown that this network is capable of generalizing from the set of specified...

Adaptive image processing a computational intelligence perspective - Blind Image Deconvolution
We will again restrict the presentation of this chapter to the popular linear image degradation model: g = Hˆ + n f (7.1) where g, f and n are the lexicographically ordered degraded image, original image and additive white Gaussian noise (AWGN), respectively [21, 145]. H is the linear distortion operator determined by the point spread function (PSF), h. Blind image deconvolution is an inverse problem of rendering the best estimates, ˆ and h,...

In this chapter, we propose an alternative solution to the problem of adaptive regularization by adopting a new global cost measure. It was previously seen that the newly formulated ETC measure is capable of distinguishing between the textures and edges in an image. It is further observed in this chapter that the distribution function of this measure value in a typical image assumes a characteristic shape, which is comparatively invariant...

In this chapter, we introduce the technique of model-based neural networks, which is to be applied to our problem of adaptive regularization in image restoration. Instead of adopting the general neural network architecture introduced in Chapter 1 for our adaptive image processing applications, we propose the use of modular model-based neural network for our purpose. We used the term “modelbased” in the sense of Caelli et al. [62], where...
