S.Vimala, P.Uma, B.Abidha . Improved Adaptive Block Truncation Coding for Image Compression. International Journal of Computer Applications. 19, 7 ( April 2011), 1-5. DOI=10.5120/2377-3133
The Block Truncation Coding (BTC) is one of the lossy image compression algorithms. In this paper, we have proposed a method called the Improved Adaptive Block Truncation Coding (IABTC) based on Adaptive Block Truncation Coding (ABTC). 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.
