A new 3-D wavelet transform(WT)coding algorithm with edge detection forblocks of image sequences is presented. The edge detection of the high-frequency areasand high-frequency frames of decomposition which had been transformed three timesby 3-D wavelet transform is done via detecting the low-frequency areas and thelow-frequency frames respectively in the same WT-level. So it doesn' t require thetransmission of any address information, and only the effective edges and edge-motionveCtors arc coed. The main at...
