We have developed a scalable image compression scheme with a good performance-complexity trade-off. Like JPEG, it is based on the 8 × 8 block discrete cosine transform (DCT), but...

We propose a new, very low complexity, single-pass, algorithm for compression of continuous tone compound documents, known as GRAFIT (GuaRAnteed FIT) that can guarantee a minimum ...

Motion estimation is a temporal image compression technique, where an n x n block of pixels in the current frame of a video sequence is represented by a motion vector with respect...
