Abstract
In image compression for subsequent transmission over a data channel it is often desirable to discard nonessential information before further coding for compression is performed. In this paper polarlog coordinate mapping is used to reduce the input image in a way that preserves high resolution in the field of interest while collapsing information at the field periphery. This reduced image is then compressed by using runlength encoding thus allowing the compressed data to be transmitted over a narrower bandwidth channel. Simulation results for compression using polarlog as a preprocessing stage are presented. Other possible preprocessing stages as well as compression stages are also discussed.
