Abstract
Lossless compression techniques are essential in archival and communication of critical applications such as medical images. A segmentation-based lossless image coding (SLIC) method has been proposed, which is based on a simple region growing procedure. The embedded region growing procedure produces a discontinuity index map, an error image data part, and a seed data part. Both the error image data and the discontinuity index map data are encoded by the Joint Bi-level Image experts Group method. The SLIC method resulted in, on the average, lossless compression to about 1.6 b/pixel from 8 b, and to about 2.9 b/pixel from 10 b. In this paper, we propose an efficient region growing method to improve the speed and to keep the lossless compression. Our method takes only about 35% execution time which is required by the original one.
