ABSTRACT
DCT has block effect and the "mosquito noise" and become more obvious in the low transmission. It is difficult to meet the satisfaction of video transmission in narrow bandwidth and high quality requirements. Video image based on mathematical morphology inter-frame coding technique is the use of inter-frame motion compensation coding algorithm through complex morphological transformation, using the structural elements of the macro block irregular pieces for opening and closing operation, selecting and filtering the irregular pieces and then estimating and encoding the small irregular size for motion and motion vector and finding the matching block with absolute difference to achieve inter-frame prediction. The simulation can achieve relatively fine compensation to improve the coding efficiency and under the same compression ratio the video quality can be improved, the deficiencies of the DCT algorithm in image transmission are remedied to improve the effect of image transmission, to reduce the computational complexity, to improve signal noise ratio. It is of great significance in decoding and transmitting the network video.
