摘要：

A simple and easy to implement method to improve the block truncation coding (BTC) is proposed for image compression. A set of predefined bit planes is defined independently of the images to be encoded. The bit rate is considerably reduced by encoding the index of the predefined bit planes using Huffman encoding. Experimental results show that at lower bit rate the proposed method provides acceptable visual quality reconstructed images.
