Picture coding system
专利汇可以提供Picture coding system专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve the coding reduction rate and to attain highly efficient coding by using a two-dimension band spatial filter or hierarchy quantization means so as to decompose an original picture into a multiplex picture by components, using an electric neuron circuit network so as to encode the decomposed picture.
CONSTITUTION: A caption 12 is a picture with an ultralow spatial frequency in DC-1Hz, a caption 13 is a picture with a spatial frequency of 1Hz-10Hz, a caption 14 is a picture with a spatial frequency of 10Hz-100Hz, and a caption 15 is a picture with a spatial frequency of 100Hz-1000Hz. The pictures are separated from the original picture subjected to filtering at each band spatial frequency 2. At first, suppose that a talker is making utterance, then the movement of the background picture and the face is very less and only the mouth is moving at a very high speed, the motion itself of the mouth is subjected to information compression by the action of a characteristic operating element neuron. Thus, the data of abstract resulting from the deformation of the mouth and the abstract data representing its moving direction are enough for the transmission.
