| Patent Number | 6393154 |
| Title | Method and apparatus for digital image compression using a dynamical system |
| Issue Date | 2002-05-21 |
| Inventor | Olurinde E. Lafe |
| Abstract | Digital images are transformed using a set of filters derived from the evolving states of cellular automata. In accordance with a preferred embodiment, the ensuing transform coefficients are encoded using a sub-band-based embedded stream technique that places the most important transform coefficients at the top of a hierarchical storage/transmission. Compression is achieved when the stream encoding/decoding is terminated after 1) a stipulated maximum bit budget is reached, or 2) when a predefined maximum error rate is attained. The present invention provides an encoding method for accelerating the transmission of image/video data through communications networks and storing the compressed data on digital storage media. |
