| Abstract: | According to different behaviors of CT 3-D medical image, image sequences are divided into small blocks. Error at boundaries between coding blocks is reduced by smoothing and overlapping boundary. A hybrid scheme of SPIHT and SPECK is used together. SPIHT is used in inter-slice and SPECK is used in intra-slice. The hybrid technique provides efficient and accurate coding of the medical images. It is better than single compression scheme. |
