Estimating the term…
Digital data representing individual pixels of a video image frame are read and then encoded as a series of binary coded words describing blocks of pixels typically eight by eight for transmission or storage. When the words are decoded an assessment is made as to when a set of pixels representing a region of the video image frame signifying an object at least overlaps into other blocks. Subregions of the blocks in question which make up the whole region are identified and their pixel luminance and chrominance values and these values are interpolated across the region to smooth out transitions across boundaries artificially delimiting the subregions. A library of masks representing luminance values for all the pixels in a block can be made available in order to enhance the compression process.
A method of processing digital video information in an adapted compressed format for transmission or storage and then decompressing the information in the compressed format to obtain reconstructed digital video information;
A method according to any one or more of the preceding claims, wherein in the case where a group or block is substantially unchanged and constant for a number of successive video image frames then the further codeword includes the number of video image frames (temporal gap) for which that group or block is unchanged.
A method according to any one or more of the preceding claims and further comprising applying antialiasing boundaries between regions on the reconstructed video image frame.
