了在取均值过程中窗口各个像素点所占的权重，也就是各个像素点的系数，这时候就称为加权均值滤波；对于中值滤波，对应-mean in the process from all pixels window share of weights, which is all the coefficient of pixels, this time called on the weighted average filter; For median filter corresponds

Image Enhancement. Takes lenna image as input, applies low pass filter, median filter, weighted and center weighted median filter. Plots the output for each image

VC6.0写的MFC程序，主要功能： 1.打开BMP格式灰度图像，按BMP格式一点一点读； 2.显示灰度图像的直方图，可以在直方图上选择阈值进行二值化，可以直方图均衡化； 3.可以保存处理后的图片； 4.灰度位图的几何变换：平移变换、旋转变换、缩放变换； 5.灰度位图的噪声抑制：“中值滤波”的模板大小采用3*3与5*5分别实现、“均值滤波”的模板大小为3*3，实现“算术平均(H0)”和“加权平均(H1、H3)”、实现高斯滤波(H2)；

加权中值滤波,用于图像增强,只用于超声图像,对超声图像去噪有很好的效果(Weighted median filter is used for image enhancement, only for ultrasonic image, has the very good effect on the ultrasonic image denoising)
