Image compression has become inevitable as we deal with lot of images which are to be transmitted or stored. Image compression techniques are helpful for reducing the cost associated with transmission and storing of images. Absolute Moment Block Truncation Coding (AMBTC) is one of the fast moment preserving lossy image compression techniques. In this paper, the performance of existing AMBTC is improved in terms of Compression Ratio by multi-level splitting of image into multi-sized blocks. The feature of `inter-pixel redundancy is exploited to improve the coding efficiency. The proposed scheme works out well for benchmark images of varying gray level distribution.
