Abstract:Block truncation coding (BTC) technique is a simple and fast image compression algorithm since complicated transforms are not used. The principle used in BTC algorithm is to use two-level quantiser that adapts to local properties of the image while preserving the first-or first-and second-order statistical moments. The parameters transmitter or stored in the BTC algorithm are statistical moments and bitplane yielding good quality images at a bitrate of 2 bits per pixel (bpp). In this paper, two algorithms for … Show more
“…Choi and Ko devised a novel DPCM-BTC [8]. Natarajan and Rao proposed two modified BTC algorithms by using the ratio of moments [9]. In BTC, input image is divided into small blocks of size 4 x 4 pixels.…”
In this paper, we have proposed an extended version of Absolute Moment Block Truncation Coding (AMBTC) to compress images. Generally the elements of a bitplane used in the variants of Block
