Two methods of static image compression - the Joint Photographic Experts Group (JPEG) and a fractal-based method - are compared in terms of the detectability of simple targets following compression and decompression of the images containing such targets. Targets consisted of rectangles of various sizes and contrasts that were embedded in images of natural terrain. Using compression ratios from 0 to 35, it was found that the loss in detectability of targets in images compressed using the fractal technique was significantly greater than the loss for the JPEG-compressed images.
