自动同时调整高斯噪声和模糊度 并生成参数与psnr对比关系三维图的程序-Program vnbpsnr is as same as program cpsnr basically but sig1 and sig 2 will be changed at the same time. I1 means original image. We just need to input the original image. The sig1(sig noise) will be test from 0.01 to 0.05 , the steplength of the loop is 0.01.　And the sig2(sig blur) will be set from 0.5 to 1.0 , the steplength of the loop is 0.1. Via this function, the changes of Psnr under 2 parameteres will be shown.
