摘要： An architecture for performing the two-dimensional discrete wavelet transform includes a transform module including a first stage and a second stage for decomposing an input image into four bands, and among the four bands, the band having the low frequency in both horizontal and vertical direction serves as the input image for next level decomposition operation; a multiplexer for selecting the band having the low frequency in both horizontal and vertical direction as the input image to feed into the transform module; and an optional memory module for storing the band having the lowest frequency in both horizontal and vertical direction. The polyphse decomposition technique is employed to the decimation filters of the first stage for segmenting the coefficients of the decimation filters of the first stage into an odd-numbered part and an even-numbered part, and the coefficient folding technique is employed to the decimation filters of the second stage such that every two coefficients of the decimation filters of the second stage share one set of a multiplier, an adder, and a register.

摘要： We discloses an efficient method for compressing a color image, visual block pattern truncation coding (VBPTC), in which the conventional block truncation coding (BTC) serves to encode an original image. This method defines the edge block according to human visual perception. If the difference between the two quantized values of BTC in a block is larger than a threshold which is defined by visual characteristics, the block will be identified as an edge block. In an edge block, the bitmap is adapted to compute block gradient orientation and to match the block pattern.

摘要： The present invention discloses a method for processing a data stream by utilizing plural processors, including the central processing unit and the compression processor of at least one MPEG card. With the similar concept of the distributed system, the present invention could make best use of each processor in the computer and therefore greatly reduce the rendering time. The steps of the method comprises: dividing the data stream into plural segments; checking states of a central processing unit and at least one compressing processor; dispatching the segments to either the central processing unit or the compressing processor according to the statuses, wherein the central processing unit or the compressing processor would process the segments to generate compressed segments; and cascading the compressed segments to generate a compressed data stream.
