Abstract

The majority of compression algorithms developed today contain some degree of image loss. While this is acceptable for certain types of image viewing, such a loss can interfere with applications that require the scientific analysis of an image. In this paper a lossless motion compensation compression algorithm is introduced and tested on a series of medical images which contain a high degree of motion. This motion compensation technique compensates for translation, scaling, rotation and the movement of multiple objects. This is accomplished be recursively dividing an image into a series of blocks, starting with a set of sixteen by sixteen size blocks, which are checked for motion and stored as a set of five bitmap files. The recursion continues until a block contains a single pixel of movement, at which point the intensity difference of the pixel from the previous and current frame is stored in a sixth file.
