Abstract
In this paper we advance an optical JPEG color image compression algorithm and discuss its performance. Statistical metrics such as Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) are used. These quality criteria quantify the difference between the original and reconstructed image. The time required for compression/decompression using our optical method is one of the considered performance factors. Simulation results are presented to illustrate the effect of the compression ratio on the reconstructed image quality.
