While improving compression ratio is a persistent interest in image representation, the encoding and decoding time is critical in some applications such as real-time image retrieval and communication. Based on the Run-Length Coding (RLC) and the Gouraud shading method, an Improved Run-Length Coding (IRLC) for gray level images is presented in this paper. The theoretical analysis and the experimental studies illustrate that the IRLC is superior to the S-Tree Compression (STC) in respect of the encoding and decoding time, without the compromises of the bit rates and the image quality.
