    摘要： Image encoding/decoding apparatus and method are disclosed. The image encoding apparatus includes: a target block splitter for splitting a target block of an input image to be encoded into a plurality of subblocks according to positions of pixels; a key block encoding unit for selecting a random key block, the size of which is larger than a pixel size of at least one of the plurality of subblocks split by the target block splitter, and performing an intra-prediction or inter-prediction encoding process on the selected key block; and a non-key block encoding unit for designating the rest of the subblocks, except for the selected key block, as a non-key block, and performing a spatial prediction process on the designated non-key block by using a key block reconstructed by the key block encoding unit and values of peripheral pixels of a current block.

    摘要： In video encoding and decoding predictions may be generated by intra-frame prediction. Intra-frame prediction uses reconstructed pixels in a reconstructed frame. Intra-frame prediction is performed by extending the reconstructed pixels into a predicted block using intra-frame prediction modes, each intra-frame prediction mode indicating a direction of the extension. In order to reduce the number of possible intra-frame prediction modes, a subset is selected from a predetermined set of possible intra-frame prediction modes. A subset of intra-frame prediction modes can be created by forming preselection sets of intra-frame prediction modes on the basis of similarity of their associated predicted blocks and selecting a representative intra-frame prediction mode from each preselection set.

    摘要： A block divider divides an input image into a plurality of regions. A prediction signal generator generates a prediction signal for the pixel signal contained in an object region, which is the object of processing, among the plurality of regions, and generates a prediction signal by using a texture synthesis method for forming a texture signal for the object region. A subtracter determines a residual signal between the pixel signal of the object region and the prediction signal, and a transformer and a quantizer encode the residual signal to generate a compressed signal.
