摘要： A subband decomposition of an image is performed by filtering the image in a progression of N line windows. In a first filter stage, vertical filters perform high and low pass filtering on each N line window. Then horizontal filtering is performed on the output of each vertical filter. The lowest subband provided by the filter stage is recursively decomposed by additional filter stages. Higher subbands of each filter stage are encoded and placed in an embedded bitstream. Block encoding can be performed in which a number of lines of each subband are coded as a plurality of blocks. The blocks of a subband are coded independently of each other. The block coding supports region-of-interest reconstruction.

摘要： A system and method are provided for encoding and compressing video data. A memory device is configured to store video data, and a corresponding memory controller controls the storage of video data in the memory device. A frame buffer compression module compresses frame data received from a video module to be stored in the memory device according to the memory controller and decompresses compressed frame data received from the memory device according to the memory controller for use by a video module. The frame buffer compression module includes a frame buffer compression encoder configured to encode and compress frame data received from a video module for storage in memory according to the memory controller. The frame buffer also includes a corresponding frame buffer compression decoder configured to decode and decompress frame data received from memory according to the memory controller for use by a video module.

摘要： Embodiments of the claimed subject matter provide a system and process for enhancing the display of color in a graphical display. In one embodiment, a process is provided for color enhancement using a detection volume and a shift volume. In one embodiment, input from pixels, as color data, is compared to a detection volume. If the color data of an input is detected in the detection volume, the color data is modified to a corresponding position in the shift volume, the modification consisting of an enhancement to the original color.

摘要： To encode an unencoded block of a frame, a search window is defined within the frame. Each pixel disposed within the search window and disposed in the unencoded portion of the frame that is assigned a value. A difference is computed between the unencoded block and each possible block within the search window. The block having the smallest difference, together with this difference are used to encode the unencoded block.
