PROGRESSIVE TECHNIQUE FOR HUMAN FACE ARCHIVING AND RETRIEVAL

A progressive region-based image compression technique is presented. T his technique is based on the second-generation image compression para digm, representing images as a union of homogeneous regions in harmony with the characteristics of the human visual system. The technique is progressive, allowing for an initial coarse version of the image to b e reconstructed quickly from the compressed image data, and then refin ed through to the desired degree of fidelity. This paper describes how this technique can be applied to human face image archiving and retri eval. Compression results are provided and comparison with the JPEG st andard is undertaken.
