Abstract
In the tactical arena, the timely receipt of imagery is of highest priority. lossy compression of the imagery for transmission increases the ability to provide imagery in a timely fashion. In the reconstruction of this imagery, some distortion is acceptable as long as the ability to extract relevant information is retained. This thesis is an independent assessment of four image compression algorithms (Joint Photographic Experts Group (JPEG) compression, Wavelet Compression, Fractal Compression and the compression algorithm contained in the Navy TENCAP sponsored Radiant Tin Program) for their ability to provide an imagery product of sufficient quality which meets the requirements of tactical users. The quantitative analysis shows that most quantitative measures are not useful for rating compression methods. In the qualitative assessment, using the Analytic Hierarchy Process, Wavelet compression appears to be the best choice of compression method across the various compression ratios. JPEG does very well at low ratios of compression as expected. Similarly, the Radiant Tin algorithm does very well at high ratios of compression. In the application of tactical imagery, fractal compression does not seem to be a good choice.
