Abstract :
Zeng (see ibid., vol.27, p.1126-8, 1991) has described an interpolative two-level block truncation coding (BTC) image compression algorithm. The authors extend the work of Zeng to a three-level interpolative BTC algorithm. Compared to Zeng, the new algorithm gives reconstructed images with substantially higher image quality with no increase in bit rate.
