Image signal transmitting system using image frames differences |
摘要 |
An image signal transmitting system uses the difference between image frames, which can transmit lots of information in a small amount of data, by transmitting the acutal moving areas which are extracted by using two change detecting masks and whose contours and textures are encoded for human visual perception. A larger amount of information is expresssed by a smaller amount of data by extracting the motion in a unit of frames, not in a unit of blocks, and expressing a converted portion by its contour and texture to facilitate the recognition of the converted portion.
