Abstract:
A moving picture encoding/decoding system comprising a moving picture encoding apparatus and a moving picture decoding apparatus,said moving picture encoding apparatus including: input image encoding means for encoding an input image signal including an image object; first storage means for storing the image signal including the image object; shape information encoding means for encoding shape information representing a shape of the image object to generate encoded shape information, and generating boundary information representing a boundary position of the image object; second storage means for storing the boundary information; and first padding means for identifying an outer region of the image object in the image signal stored in said first storage means on the basis of the boundary information stored in said second storage means, calculating a pixel value to be substituted into the outer region, the calculating being performed using information from pixels at the boundary position and from no other pixels of the image object and substituting the pixel value into the outer region stored in said first storage means, and said moving picture decoding apparatus including: image decoding means for referring to a reference image, and decoding encoded image data including the image object to generate a decoded image signal; third storage means for storing the decoded image signal and supplying the decoded image signal as a reference image in a next frame decoding processing to said image decoding means; shape information decoding means for decoding encoded shape information serving as encoded data of image object shape information to generate shape information, and generating boundary information representing a boundary position of the image object; fourth storage means for storing the boundary information; and second padding means for identifying the outer region of the image object in the image signal stored in said third storage means on the basis of the boundary information stored in said fourth storage means, calculating a pixel value to be substituted into the outer region the calculating being performed using information from pixels at the boundary position and from no other pixels of the image object, and substituting the pixel value into the outer region stored in said third storage means.
