A fast image coding method based on dictionary

A fast image coding method based on dictionary is introduced firstly. This method gets more image information by fewer characters and can increase the coding efficiency. It improves the matching progress by the domination blocks which are generated with fixed dictionary. The advantage of this method is that different images can be generated with the same fixed dictionary set. The results of experiments show that this fast image coding method uses less time than other image coding methods under the requirement of high quality of decoding images.
