摘要： A generalized scan interleaving-based encoding/decoding method using context values of neighboring pixels and an apparatus therefore, and linear down/up-sampling apparatus used in the apparatus are provided. If the down-sampling ratio is m/n, the linear down-sampling apparatus divides the down-sampling ratio into two parts, [1/2K9 and [(m2K)/n], and performs linear down-sampling by applying the two parts sequentially. If the up-sampling ratio is n/m, the linear up-sampling apparatus divides the up-sampling ratio into two parts, [n/(m2K)] and [2K], and performs linear up-sampling by applying the two parts sequentially. By applying the linear down-sampling and up-sampling method to existing generalized an interleaving-based encoding using context values of neighboring pixels, continuously-scalable down-sampling is enabled and by using the down-sampled base layer, the current layer can be encoded and decoded.

摘要： Shape information is scalably encoded and decoded by interleaved scan line (ISL) and raster scan line (RSL) methods and the encoded and decoded shape information is used for encoding texture information. The shape information of a chrominance (UV) component is encoded to compensate for the chrominance (UV) component. The encoding method is independently applied to the shape and texture component of each block. A scalable encoder of a still image using wavelets compresses pixels by using the characteristics between ISL pixels in a shape of the layer to be encoded or pixels between two layers in encoding the shape between layers. It is therefore possible to restore the shape and texture at high speed by performing the scalable encoding according to resolution, such as for searching for an image in a database/library. Also, tile coding a large image field to independently restore desired parts is fast and efficient.

摘要： A video signal encoding and/or decoding method based on adaptive lattice quantization. An input frame of a video sequence is partitioned into blocks of pixel data called vectors. The set of the vectors is partitioned into blocks called macroblocks. The vectors in each macroblock are subjected to lattice vector quantization which examines the range of vector components in multiple dimensions and adjusts the density of lattice vectors in accordance with the range of vector components. Quantization unit replaces each input vector for a nearest lattice vector in multidimensional space. Each quantized vector in the macroblock is converted into an index of a lattice vector. An overhead information about the range in a macroblock and set of indices with or without subsequent Huffman or Arithmetic coding is transmitted to or stored in the receiver end.
