Image compression is an essential technique for efficient transmission and storage of images. The demands for transmission and storage of multimedia data are increasing exponentially. A gray scale ...

Image compression, once the domain of the PC, is becoming pervasive in embedded environments. This trend is largely a result of the increased processing power and multimedia capabilities of new DSPs.

Earlier in this column, we looked at various artifacts introduced in the compression process, such as mosquito noise, contouring and blockiness, including basis functions. This month, we'll examine ...

Image compression, once the domain of the PC, is becoming pervasive in embedded environments. This trend is largely a result of the increased processing power and multimedia capabilities of new DSPs.

While we all know that compression causes artifacts, just how much do you know about what causes them and how to reduce them? While the occurrence of artifacts would seem random, it is directly linked ...
