This paper represents lossy compression technique which can be effectively used for correlated pixels in both continuous and discontinuous series. Generally, compression is achieved by reducing redundancy through removal of similar pixels. Here, dependency of effective compression over their continuity has been removed. The efficiency of the proposed method has been described mathematically, proving it suitable for higher bit images. KeywordsCompression Ratio, Run length encoding.

This paper describes a unique method of recognizing common patterns among various images. It makes use of signatures of images which enables it to overcome the problem of different features ordering and appearance of noisy and less expressive features. It discusses two different methods of finding common set of data among various signatures. It has been then concluded that the proposed algorithm would be very suitable for continuous tone images with high contrast patterns.
