Discrete Cosine Transform by K. Ramamohan Rao,P. Yip Pdf

This is the first comprehensive treatment of the theoretical aspects of the discrete cosine transform (DCT), which is being recommended by various standards organizations, such as the CCITT, ISO etc., as the primary compression tool in digital image coding. The main purpose of the book is to provide a complete source for the user of this signal processing tool, where both the basics and the applications are detailed. An extensive bibliography covers both the theory and applications of the DCT. The novice will find the book useful in its self-contained treatment of the theory of the DCT, the detailed description of various algorithms supported by computer programs and the range of possible applications, including codecs used for teleconferencing, videophone, progressive image transmission, and broadcast TV. The more advanced user will appreciate the extensive references. Tables describing ASIC VLSI chips for implementing DCT, and motion estimation and details on image compression boards are also provided.

Discrete Cosine Transform, Second Edition by Humberto Ochoa-Dominguez,K. R. Rao Pdf

Many new DCT-like transforms have been proposed since the first edition of this book. For example, the integer DCT that yields integer transform coefficients, the directional DCT to take advantage of several directions of the image and the steerable DCT. The advent of higher dimensional frames such as UHDTV and 4K-TV demand for small and large transform blocks to encode small or large similar areas respectively in an efficient way. Therefore, a new updated book on DCT, adapted to the modern days, considering the new advances in this area and targeted for students, researchers and the industry is a necessity.

Perceptual Image Coding with Discrete Cosine Transform by Ee-Leng Tan,Woon-Seng Gan Pdf

This book first introduces classic as well as recent computational models for just-noticeable-difference (JND) applications. Since the discrete cosine transform (DCT) is applied in many image and video standards (JPEG, MPEG-1/2/4, H.261/3), the book also includes a comprehensive survey of computational models for JND that are based on DCT. The visual factors used in these computational models are reviewed in detail. Further, an extensive comparative analysis of these models using quantitative and qualitative performance criteria is presented, which compares the noise shaping performance of these models with subjective evaluation and the accuracy between the estimated JND thresholds and subjective evaluation. There are many surveys available on computational models for JND; however, these surveys seldom compare the performance of computational models that are based on DCT. The authors’ survey of the computational models and their in-depth review of the visual factors used in them will help readers understand perceptual image coding based on DCT. The book also provides a comparative analysis of several perceptual image coders that are based on DCT, which are compatible with the highly popular and widely adopted JPEG standard.

D C-T! by Joana Avillez,Molly Young Pdf

A joy-inducing illustrated book about New York City in the ingenious style of William Steig's classic CDB! Just as there are few cities as storied and replete with life as New York City, there are few illustrators or writers who have charmed as many generations as William Steig. To Molly Young and Joana Avillez, a connection between the two seemed obvious, and so D C-T! ("The City!") was born. Using a playful phonetic language first invented by Steig in his now classic 1968 book CDB!--but which in today's world of text message and internet shorthand feels uncannily contemporary--Young and Avillez tell a different story on each page of this collection of illustrations stuffed to brim with humor and cleverness: • "S L-I-F!" (It's alive!) A boy shouts gleefully at a pile of rubbish seething with rats • "I M B-Z" (I'm busy) Declares the phone-wielding businesswoman to the would-be mugger • "R U I?" (Are you high?) Asks the clerk at a bodega to the blissed out shopper Brought to life in Avillez's distinctively ebullient and droll style are precocious pets and pet-owners, iconic architecture, and startlingly intrepid anthropomorphic rats. At once recognizable, and imagined like never before, are the surprising, intoxicating, and not-always-entirely-welcome sights, sounds, and smells of New York City. Full of wit, romance, and sheer delight, D C-T! is both an affectionate portrait of the visual cornucopia that is New York City and a gracious love letter to the great William Steig, sure to enchant readers young and old alike just as his work has for half a century.
