Description: 根据图像小波分解的特点和小波分解后高频小波系数的统计特性,构造了一种新阈值函数的去噪算法。
与传统的硬阈值、软阈值函数相比,新阈值函数考虑了图像能量分布的特点,对于每一小波系数乘以一个与自身大小相
关的降噪因子,并且新阈值函数简单易于计算,具有较强的自适应性-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 Platform: |
