    摘要: Provided are a method and apparatus for encoding and decoding an image. The method of encoding an image includes generating half-tone data by applying patterns specified by each color channel to input data, rearranging the generated half-tone data according to the characteristics of the applied patterns, and predicting the rearranged half-tone data and encoding the predicted half-tone data. Therefore, encoding and decoding can be performed more efficiently and a compression rate can be improved.

    摘要: Provided are methods and apparatuses for converting a lower bit-plane image, and methods and apparatuses for inverse-converting the lower bit-plane image, which increase the correlation of the lower bit-plane image. According to the method of converting a lower bit-plane image, pixels of the lower bit-plane image are sequentially added or subtracted so as to generate a converted lower bit-plane image. Accordingly, the lower bit-plane image has higher regularity, and thus the efficiency of image processing using the lower bit-plane image is improved.

    摘要: A method and apparatus for generating video packets and a method and apparatus for restoring video are provided. The method of generating video packets includes: generating at least one pixel block consisting of at least one reference pixel and a plurality of neighboring pixels adjacent to the at least one reference pixel from pixels of a video frame; replacing pixel values of the neighboring pixels in the at least one pixel block with pixel difference values, which are difference values between a pixel value of one of pixels adjacent to the neighboring pixels and the pixel values of the neighboring pixels; generating packets so that a pixel value of the at least one reference pixel and the pixel difference values of the neighboring pixels are allocated to different packets according to positions of the pixels; and performing entropy coding of some of the packets including the pixel difference values of the neighboring pixels.
