双边滤波(Bilateral filter)是一种可以保边去噪的滤波器。之所以可以达到此去噪效果,是因为滤波器是由两个函数构成。一个函数是由几何空间距离决定滤波器系数。另一个由像素差值决定滤波器系数。-Bilateral filter (Bilateral filter) is a security edge de-noising filter. The reason why this denoising effect can be achieved because the filter is

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.
