摘要 |
A region-based system, method and architecture for encoding and decoding digital still images to produce a scalable, content-based, randomly accessible compressed bit stream is disclosed. According to the system, raw image data is decomposed and ordered into a hierarchy of multi-resolution sub-images. Regions of interest are then determined. A region mask is defined to identify the regions of interest and then encoded. This data is then sorted on the basis of the magnitude of the multi-resolution coefficients to produce the scalable, content-based randomly accessible compressed bit stream. |
