Abstract Broad-based lossy compression techniques are developed for efficient image data compression. Discrete Cosine Transform (DCT) has become the industry standard. Vector Quantization (VQ) is a relatively new coding technique. VQ image compression has become realities [sic] and practical algorithm in fast codebooks design with LBG algorithm. Hybrid DCT-VQ scheme takes advantage of both VQ and transform coding techniques and presents the basic principles of...

Abstract Motion compensation is one of the important basic building blocks in image processing especially for images having temporal redundancy (correlation between different frames in a sequence of images). The process of determining the movement of objects within a sequence of images is known as motion compensation. Processing images accounting for the presence of motion is called motion compensated image processing. Among the various advantages it offers, the biggest advantage lies in the fact...
