摘要： A non-transitory recording medium including a program is provided. The program causes a processor to divide a picture into tiles. The tiles are coded to generate pieces of coded data, each of which corresponds to a different one of the tiles. In this regard, a first tile of the tiles is coded with reference to coding information of an already-coded tile neighboring the first tile when a boundary between the first tile and the already-coded tile is a first boundary. The first tile is coded without reference to the coding information of the already-coded tile when the boundary between the first tile and the already-coded tile is a second boundary. A bitstream including the pieces of coded data is generated. The bitstream includes tile boundary independence information which indicates whether each boundary between the tiles is one of the first boundary and the second boundary.

摘要： Automatic characterization or categorization of portions of an input multispectral image based on a selected reference multispectral image. Sets (e.g., vectors) of radiometric descriptors of pixels of each component of a hierarchical representation of the input multispectral image can be collectively manipulated to obtain a set of radiometric descriptors for the component. Each component can be labeled as a (e.g., relatively) positive or negative instance of at least one reference multispectral image (e.g., mining materials, crops, etc.) through a comparison of the set of radiometric descriptors of the component and a set of radiometric descriptors for the reference multispectral image. Pixels may be labeled (e.g., via color, pattern, etc.) as positive or negative instances of the land use or type of the reference multispectral image in a resultant image based on components within which the pixels are found.

摘要： A method, system and computer software product for improving rate-distortion performance while remaining faithful to JPEG/MPEG syntax, involving joint optimization of Huffman tables, quantization step sizes and quantized coefficients of a JPEG/MPEG encoder. This involves finding the optimal coefficient indices in the form of (run, size) pairs. By employing an interative process including this search for optimal coefficient indices, joint improvement of run-length coding, Huffman coding and quantization table selection may be achieved. Additionally, the compression of quantized DC coefficients may also be improved using a trellis-structure.

摘要： A compressor includes a memory storing a de-compression pixel value de-compressed after a pixel value is compressed, a direct compression unit compressing a pixel value corresponding to a compression target pixel, and a first difference compression unit configured to compress a difference value between the pixel value corresponding to the compression target pixel and a decompression pixel value corresponding to at least one reference pixel, an error evaluation unit, and a decompression unit. The error evaluation unit compares a pixel value error of the direct compression unit before and after compression with a difference value error of the first difference compression unit before and after compression and outputs a compression value obtained through compression of the direct compression unit or a compression value obtained through compression of the first difference compression unit together with an identifier indicating a compression method, based on the comparison result, to the decompression unit.

摘要： An example method includes interpreting compressed source data to produce a set of representative colors and modulation data. Portions of the modulation data are interpreted as a plurality of vectors. Each vector pertains to a respective region of the image, which has multiple portions, each with elements. Modulation data is interpreted to include vector modifier data. A respective color for each element within a first portion of the region is determined from the set of representative colors, which are combined according to a selected vector (can be a selection made from a subset of the plurality). Colors for elements in other portions of the region are determined by selecting a vector, modifying the vector according to vector modifier data, and applying the modified vector with the set of representative colors to produce colors for elements in the region. Aspects include systems and methods for source data compression and image reconstruction.

摘要： The restoration of images by vector quantization utilizing visual patterns is disclosed. One disclosed embodiment comprises restoring detail in a transition region of an unrestored image, by first identifying the transition region and forming blurred visual pattern blocks. These blurred visual pattern blocks are compared to a pre-trained codebook, and a corresponding high-quality visual pattern blocks is obtained. The high-quality visual pattern block is then blended with the unrestored image to form a restored image.
