To obtain a coder in which a motion compensation circuit is not doubly used for a picture noise elimination circuit and a picture compression coding circuit, the light weight of a camera is realized and the information generating quantity of the picture coder is reduced by eliminating noise for ...
Picture coding using pseudo-random noise In order to transmit television pictures over a digital channel, it is necessary to send a binary code which represents the intensity level at each point i... L Roberts - 《Information Theory Ire Transactions on》 被引量: 303发表: 2003年 Research on ...
A noise detection method comprising processing the image for each of the motion compensation prediction and the block unit and the quantized orthogonal transform are extracted from the code sequence encoded for each block contained in the orthogonal transform coefficient and the motion vector coding ...
PICTURE CODING DEVICE AND PICTURE NOISE ELIMINATION DEVICEPURPOSE: To obtain a coder in which a motion compensation circuit is not doubly used for a picture noise elimination circuit and a picture compression coding circuit, the light weight of a camera is realized and the information generating ...
A moving picture coding/decoding method and apparatus having a spatially scalable architecture and a signal-to-noise ratio (SNR) scalable architecture together is provided. The coding method includes the steps of down sampling shape information and texture information by a predetermined ratio to ...
In this paper; we proposed a new coding method for quality improvement of re-encoded picture which was converted from JPEG to JPEG2000. First, we considered the influences caused by block artifacts of JPEG picture and then the reduced particular wavelet coefficients in 1HL, 1LH and 1HH ...
