A modified three level Block Truncation Coding for image compression
D. Anil, Kadava. R. N. Karthik, Krishna Kumar · 2011
Block Truncation Coding (BTC) is a lossy data compression technique used for compression of images. BTC is a simple and fast image compression algorithm with less computational complexity than former schemes proposed. In this paper we propose a modified three-level BTC with an improved compression factor. Experimental results show that the suggested image compression methodology yields an image with better quality, low bit rate and lower computational complexity than the conventional three-level BTC.
