Identifier: b2125203
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...
