摘要：
A color image compression method based on a genetic algorithm and absolute moment block truncation coding (BTC) is proposed. Color images comprise three planes: red, green, and blue. There are very high correlations between the images in these planes. This motivates the use of one common bitmap to represent all three color bitmaps. In order to generate such a bitmap so that the average mean squared error between original and reconstructed images is a minimum, the genetic algorithm is applied. Comparison of results with various methods have verified that the proposed method has higher performance than the other schemes for single bitmap ETC coding of color images.
