Introduction to Digital Signal Processing and Filter Design ReviewThe book is good but the example's are the easy one.Introduction to Digital Signal Processing and Filter Design OverviewA practical and accessible guide to understanding digital signal processingIntroduction to Digital Signal Processing and Filter Design was developed and fine-tuned from the author's twenty-five years of experience teaching classes in digital signal processing. Following a step-by-step approach, students and professionals quickly master the fundamental concepts and applications of discrete-time signals and systems as well as the synthesis of these systems to meet specifications in the time and frequency domains. Striking the right balance between mathematical derivations and theory, the book features:* Discrete-time signals and systems* Linear difference equations* Solutions by recursive algorithms* Convolution* Time and frequency domain analysis* Discrete Fourier series* Design of FIR and IIR filters* Practical methods for hardware implementationA unique feature of this book is a complete chapter on the use of a MATLAB(r) tool, known as the FDA (Filter Design and Analysis) tool, to investigate the effect of finite word length and different formats of quantization, different realization structures, and different methods for filter design. This chapter contains material of practical importance that is not found in many books used in academic courses. It introduces students in digital signal processing to what they need to know to design digital systems using DSP chips currently available from industry.With its unique, classroom-tested approach, Introduction to Digital Signal Processing and Filter Design is the ideal text for students in electrical and electronic engineering, computer science, and applied mathematics, and an accessible introduction or refresher for engineers and scientists in the field.An Instructor's Manual presenting detailed solutions to all the problems in the book is available online from the Wiley editorial department.An Instructor Support FTP site is also available.

Neuropsychology of Art: Neurological, Cognitive and Evolutionary Perspectives (Brain, Behaviour and Cognition) ReviewIntrigued by the promise of its title, I zipped over to my local university library as soon as this book came in. Alas, this is not only the last word on the topic, it is not even an adequate summary of recent work.
The author is a neuroscientist herself, but the usual penetrating and synthesizing insight of such specialists seems lacking here. In her chapters on musical art and brain damage, I miss the central focus of this kind of study: the scientist learns about brain function from those who have lost a specific piece of it. Zaidel refers to some interesting studies and historical anecdotes (musicians who sustained this or that kind of brain damage), but I the reader do not learn what I want to from the discussions. I learn details, but the stories and studies do not cumulate in a big picture. Of course modern brain research is still developing, yet other researchers give me more of a sense that they can intuit a big picture beyond what they can clearly see.
Also in the music section, Zaidel's end-of-section paragraph of summary does not include major insights derived from Isabelle Peretz, one of the foremost neuroscientists of music, though Zaidel cites a couple of Peretz' publications in her bibliographies. Peretz gives a significantly better explanation of currently understood brain processing of musical phenomena than Zaidel does, but you wouldn't know from this book. It's not a bad book, just not a great one.Neuropsychology of Art: Neurological, Cognitive and Evolutionary Perspectives (Brain, Behaviour and Cognition) OverviewThe significance of art in human existence has long been a source of puzzlement, fascination, and mystery. In Neuropsychology of Art, Dahlia W. Zaidel explores the brain regions and neuronal systems that support artistic creativity, talent, and appreciation.Both the visual and musical arts are discussed against a neurological background. Evidence from the latest relevant brain research is presented and critically examined in an attempt to clarify the brain-art relationship, language processing and visuo-spatial perception. The consequences of perceptual problems in famous artists, along with data from autistic savants and established artists with brain damage as a result of unilateral stroke, dementia, or other neurological conditions, are brought into consideration and the effects of damage to specific regions of the brain explored. A major compilation of rare cases of artists with brain damage is provided and the cognitive abilities required for the neuropsychology of art reviewed.This book draws on interdisciplinary principles from the biology of art, brain evolution, anthropology, and the cinema through to the question of beauty, language, perception, and hemispheric specialization. It will be of interest to advanced students in neuro-psychology, neuroscience and neurology, to clinicians and all researchers and scholars interested in the workings of the human brain.

Going Visual: Using Images to Enhance Productivity, Decision-Making and Profits ReviewThis book aims at making corporate and marketing directors to realize that we have entered a culture of images and videos. It covers well some of the consequences of this mutation from writing to visual. Admittedly, lots of situation are covered to advocate for anticipating actions in the image civilization, and suggestions are made on how to do it. As a matter of fact, the discoveries of Neuro-sciences including Neuro-marketing (not covered in the book) explain why this phenomenum does happen. At a practical level, the successes of MySpace and YouTube (after the not so recent development of TV ads) should be sufficient evidence.
The book however does not refer to the problems linked to the daily use of images by the professional world (mainly the necessity to index them for database treatment or simply for searching, filing and handling). Machines do not know how to recognize if there is a blond guy on a picture in the middle of several other individuals, when they can do this selection with texts. There is a huge amount of research going on to solve such complex problems which have more consequences than it seems and the author simply does not even touches these aspects. Amazon's mechanical turk was created precisely for such reasons. Some scientists try to use the sound track of videos to that effect... This book totally misses these issues.
In brief a great topic properly advocated but imperfectly analyzed and not exhaustively covered. Reality doesn't need to be advocated, it lands by itself ; virtue for books (which are in depth studies) lays in detailed solutions and this book comes short on this.Going Visual: Using Images to Enhance Productivity, Decision-Making and Profits OverviewHow and why to make visual communication a powerful competitive toolFrom digital cameras and camera phones to videoconferencing, visual communication technology is changing not only personal lives but global business relationships and communities of interest. Visual communication is an essential tool for every corporation-in any industry-that wants to stay competitive.Going Visual demonstrates how businesses can harness the power of digital images and video to communicate comprehensively and unambiguously. Through real-world success stories the authors outline a clear, simple, five-step plan for developing a Visual Communication Strategy that will sharpen every organization's competitive edge and improve its bottom line.Alexis Gerard (San Mateo, CA) is the founder of Future Image Inc., an imaging technology think tank whose clients include Adobe, Canon, Eastman Kodak, IBM, Intel, Procter & Gamble, and Sony. He previously held executive positions in new technologies marketing at Apple Computer. Bob Goldstein (Los Angeles, CA) has been the president and founder of ZZYZX Visual Systems, president of the Altamira Group, and a visual communication consultant to such companies as Eastman Kodak, Apple, Oracle, Microsoft, Intel, and Hewlett-Packard. Gerard and Goldstein have coauthored articles in Red Herring and Forbes.

Photography: The Key Concepts ReviewThis is a reasonably academic review about the philosophical and cultural impact of photography in recent history. It would likely work best as a supplimental college textbook for photographic theory at the post and undergraduate level. Concise and certainly worth one's time to read. Well broken down into short chapters and sections and is highly accessible as a result.Photography: The Key Concepts OverviewIt is hard to imagine anyone's everyday life without photography being involved in some way, from passport photographs, to publicity, postcards, magazines and art galleries. Photography is one of the most pervasive media and consequently difficult to grasp as a single thing. Associated with both science and art from its beginning, photography crosses many boundaries and, with the advent of digital imaging and manipulation, it has extended its presence even further. This book boils down the massive territory of photography to the key genres, discussing each in turn to show how they have become even more relevant in today's dynamic cultural and technological context. Illustrated with a range of historical and contemporary images and case material, this book is essential reading for anyone interested in photography.

The Psychology of Art and the Evolution of the Conscious Brain (Mit Press/Bradford Books Series in Cognitive Psychology) ReviewThis author has a good knowledge of his subject. His earlier book is wonderful with insight. This book is a revamp of that material with a summary of some recent research. For my needs the first book is more to my taste.The Psychology of Art and the Evolution of the Conscious Brain (Mit Press/Bradford Books Series in Cognitive Psychology) OverviewHow did the human brain evolve so that consciousness of art coulddevelop? In The Psychology of Art and the Evolution of the Conscious Brain, RobertSolso describes how a consciousness that evolved for other purposes perceives andcreates art.Drawing on his earlier book Cognition and the Visual Arts and ten yearsof new findings in cognitive research (as well as new ideas in anthropology and arthistory), Solso shows that consciousness developed gradually, with distinctcomponents that evolved over time. One of these components is an adaptiveconsciousness that includes the ability to imagine objects that are not present--anability that allows us to create (and perceive) visual art.Solso describes theneurological, perceptual, and cognitive sequence that occurs when we view art, andthe often inexpressible effect that a work of art has on us. He shows that there aretwo aspects to viewing art: nativistic perception--the synchronicity of eye andbrain that transforms electromagnetic energy into neuro-chemical codes--which is"hard-wired" into the sensory-cognitive system; and directed perception, whichincorporates personal history and knowledge--the entire set of our expectations andpast experiences. Both forms of perception are part of the appreciation of art, andboth are products of the evolution of the conscious brain over hundreds of thousandsof years.Solso also investigates the related issues of neurological and artisticperception of the human face, the effects of visual illusions, and the use ofperspective. The many works of art used as examples are drawn from a wide range ofartistic traditions, from ancient Egypt to Africa and India and the EuropeanRenaissance.
