    摘要： A video decoding apparatus includes: a splitter configured to split an image into at least one block; a predictor configured to predict a current sample by using at least one of a value obtained by applying a first weight to a first sample predicted earlier than the current sample in a current block and being adjacent to the current sample in a horizontal direction and a value obtained by applying a first weight to a second sample predicted earlier than the current sample in the current block and being adjacent to the current sample in a vertical direction; and a decoder configured to decode the image by using a residual value of the current sample obtained from a bitstream and a prediction value of the current sample.

    摘要： An image code conversion device for image information and its method are provided. By extracting a plurality of features of an image based on raw image information taken by an image reading device and converting the features into a unique code, the image code conversion device for image information and its method can stably convert the same image into the same image code.
    Raw image information acquired by an image reading device is converted into a plurality of pieces of developed image information on the basis of geometrical or physical factors. From the plurality of developed image information, feature information is quantified by a self-organization processing based on a probability scale. The quantified feature information is converted into a digital code. Accordingly, a unique image code corresponding to the raw image information is generated.

    摘要： The present principles provide a method and an encoder for encoding an image frame. The method includes generating, with a processor, for each block in the image frame a prediction block based on at least a prediction method; generating a scaling factor and an offset for adjusting the prediction block; and transforming the prediction block into an adjusted prediction block based on the scaling factor and the offset. The encoder includes a processor configured to, for each block in the image frame, generate a prediction block based on at least a prediction method and generate a scaling factor and an offset for adjusting the prediction block and to transform the prediction block into an adjusted prediction block based on the scaling factor and the offset. The scaling factor and offset minimize error between the block and the adjusted prediction block.
