This paper describes a new single bit-map block truncation coding (SBBTC) scheme that works with a Hopfield neural network (HNN) for the coding of color images. An incoming color block is encoded using three block-truncation coding (BTC) encoders with a common bit map for each of the three primary color planes. An HNN is used to generate a good single bit map in the SBBTC by clustering the color vectors in the block into two classes. The considering block is then encoded by the generated bit map and the two reconstruction colors each associated to one of the two classes. In comparison with other existing methods, the proposed color BTC gives the best mean-square error (MSE) performance at the same bit rate.
