针对图像中的高灰度区和灰度剧变区,应用图像局部均值和方差自适应调节增强系数。
For regions with high grey-scale level or with tensely variable grey level, the image enhancement coefficients shall be adaptively controlled based on local mean value and variance.
通常采用LMS算法对自适应横向滤波器的加权系数进行调节。
The LMS algorithm is usually adopted to adjust weight coefficients of the adaptive transversal filter whose output is an estimation of the echo signal.
