Abstract: Block truncation coding (BTC) technique has attracted much attention during the last few years as a simple source coding method to achieve good quality image reproduction by preserving the first two statistical moments of an image: the mean and the variance. It significantly reduces the amount of computation required by the traditional coding methods, such as transform. In this paper, we have proposed a method called the Improved Adaptive Block Truncation Coding (IABTC) based on Adaptive Block Truncation Coding (ABTC).And we are implemented it on LCD overdrive for image compression. The feature of inter-pixel redundancy is exploited to reduce the bit-rate further by retaining the quality of the reconstructed images. The proposed method outperforms the existing BTC based methods both in terms of bit-rate and PSNR values.
