چکیده مقاله:

This article proposes fast and lossless image compression algorithm. Proposed algorithm at first, computes difference value of (RGB) of pixel from previous pixel then, encodes high value bits of R, G, B to form of (Rh Gh Bh) by symmetrical codes. Symmetrical codes are reversible variable-length codes which are exported of symmetrical binary tree. Also this article proposed and introduced two symmetrical reversible variable-length codes with different compression results.
