A method of block truncation coding for color image compression
Takio Kurita, N. Otsu · IEEE Transactions on Communications · 1993
A basic color block truncation coding (CBTC) algorithm for color image compression is described. A modification of the algorithm that reduces truncation errors is also described. The block statistics related to CBTC methods are investigated. Some experimental results are given for a 256-*256-pixel color image with 24 b/pixel.>
