According to the characteristics of image wavelet decomposition and wavelet decomposition after the high-frequency statistical characteristics of wavelet coefficients, construct a new threshold function of the denoising algorithm. With the traditional hard threshold and soft threshold function, the new threshold function takes into account the characteristics of the image energy distribution, for each wavelet coefficient multiplied by a size associated with self-noise factor, and the new threshold function simple easy calculation, has a strong self-adaptability
