An adaptive 3-D discrete cosine transform coder for medical image compression.

An adaptive 3-D discrete cosine transform coder for medical image compression.

A new three-dimensional (3-D) discrete cosine transform (DCT) coder for medical images is presented. In the proposed method, a segmentation technique based on the local energy magnitude is used to segment subblocks of the image into different energy levels. Then, those subblocks with the same energy...
