bit plane codingEBCOT architectureTo overcome many drawbacks in the current JPEG standard for still image compression, a new standard, JPEG2000, is under development by the International Standard Organization.
The two scenarios in Example 11.1 illustrate the problems of synchronization loss in VLC, demonstrating the subtle differences between synchronization at bitstream, symbol and coding unit (e.g. transform block) levels. Example 11.1 Loss of VLC synchronization due to a single bit error Given the ...
The peak signal-to-noise ratio of the reconstructed image can gain up to 7 and 1.69 dB over JPEG and JPEG2000 under the same compression ratio, respectively. By utilizing the cloud resources, our coding scheme showed an obvious advantage in terms of visual quality. The details in the image...

(2021) introduced a multi-directional bit-level diffusion technique in which each bit plane of the plaintext image is shifted vertically and horizontally to eliminate meaningful information. Zhou et al. (2022) determined random coordinates with chaotic sequences and designed two crossover confusion ...

An image encoding apparatus comprises first processing means for determining whether or not each bit in a bit plane of a code block should be processed in a first pass, and second p
FIG. 2 illustrates a conventional binary weighted 8-bit PWM scheme. In this scheme, each event has a distinct duration which is half that of its predecessor. In this way, the intensity of the pixel can be selected using conventional binary coding. In the general weighted case, the frame-ti...
