摘要： There is provided an improved scan interleaving method suitable for multipurpose encoding of binary image data, and for selectively encoding a part or the whole of object image data according to presence or absence of exceptional sampling data (ESD). In the present invention, when the pixel data of base image data and the corresponding pixel data of the object image data to be scan-interleaved are the same (in the case of predictive sampling data), no encoding is performed on the pixels of the object image data which have no ESD, thus simplifying the algorithm and system implementation. As a result, the overall encoding performance can be improved.

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.
