Abstract Taking the normal distribution as an example, this article discusses the problems of minimized entropy quantization in image compression, including single coefficient entropy quantization and multi-coefficients entropy quantization. It provides a quantization theory for different compression ratios.

Key words： Image compression Quantization Information entropy Adjustable
