Image compression using BTC and AMBTC
S. K. Kapde, S.V. Patil · International journal of advanced research in computer science and electronics engineering · 2012
the present work investigates image compression. Two algorithms were selected namely; block truncation coding (BTC) and Absolute Moment block truncation coding (AMBTC) and a comparative study was performed. The Block Truncation Coding (BTC), Absolute Moment block truncation coding (AMBTC) are the lossy image compression algorithms. These are simple and easy to implement image compression algorithms. The basic BTC and AMBTC algorithm is a lossy fixed length compression method that uses a Q level quantizer to quantize a given region of the image. Both of two techniques rely on applying divided image into non overlapping blocks. They differ in the way of selecting the quantization level in order to remove redundancy.
