PIC单片机的CCP功能
//220V的交流电源直接用电阻限流,经光耦隔离,形成脉冲送到CCP2,
//CCP2模块的捕捉功能,设置为每16个上升沿捕捉一次,相当于平均滤波,目的是为了减小误差
//TMR1计数的分频系数计算:假设电源为50Hz,即一个周期为20ms,16个周期为320ms
//320ms=320000us,单片机用4MHz晶振,指令周期为1us,设TMR1的分频系数为K:65536×K=320000
//得K=4.88,取K=8,即TMR1的预分频系数设为1

通过观察图像lena_noise.bmp可以看到,该图像主要包含高斯噪声、椒盐噪声等。
通过查阅资料可知,维纳滤波可以很好的滤除高斯噪声,而中值滤波对于椒盐噪声的滤出效果优异,因此本次采用维纳+中值的滤波方式进行图像的去噪处理。
图像常用评价方法有:信噪比、相关系数、清晰度。信噪比较为常用;相关系数 由于滤波会使原图像失去某些细节,因此这种评价方式为参考性指标而非绝对评判标准;清晰度 为图像子块的方差
综合考虑采用图像的峰值信噪比(PSNR)作为评价去噪效果指标(自编PSNR.

噪声抑制的两个关键环节为建立真实后向散射系数的估计机制和制定同质区域像素样本的选择方案。Lee滤波是利用图像局部统计特性进行图像斑点滤波的典型方法之一,其是基于完全发育的斑点噪声模型,选择一定长度的窗口作为局部区域,假定先验均值和方差可以通过计算局域的均值和方差得到。-Two key aspects of the estimated noise suppression mechanisms for the establishment of the backscattering coefficie
