| Abstract: | In this paper, the statistical properties between sub-images of wavelet transform coefficients of medical imapes are Studicd. According to the characteristic of medical images, a new wavelet based medical image coding scheme is proposed. Experiments show that the scheme outpefforms the JPEG standard. Meanwhile, the scheme supports progressive transmission so it can be satisfied with the need of medical image storape, communication and archiving. |
