    摘要: Systems, methods and computer readable media are disclosed for improving compression efficiency and quality in a remote session via tile image classification and variable encoding. A server determines a set of codecs that are shared by both the server and a corresponding client. Then, when it receives an image, it determines whether classification of the image is required. Where classification of the image is not required, the server sends the client the image, either uncompressed or compressed with a default codec and default fidelity. Where classification of the image is required, the server classifies the image (e.g. the image comprises either text or photograph), and based on that classification determines a codec with which to encode the image, and a fidelity to use on the encoding. The server performs that encoding with the codec and the fidelity, and then sends this encoded image to the client.

    摘要: This invention generates efficient encoded data to restore original image data from reduced image data. An input unit inputs block data of 2×2 pixels from original image data. A converter generates reduced image data having a size smaller than the original image data by sampling one pixel data at a preset position in the input block data. A generator generates encoded data to restore three non-sampling target pixel data in each block data so as to restore the original image data from the reduced image data generated by the resolution converter. To do this, the generator determines whether all non-sampling target pixels in a block of interest are restorable from a sampling target pixel in the block of interest or from sampling target pixels in three blocks adjacent to the block of interest, and generates and outputs three kinds of additional information based on the determination result.
