Can we type the formula like this: psnr=20.0* (log10(1/sqrt(mse)));
I mean can we write 1 intstead of 255.
Plz explain.

Hi Faizullah
We can use 1 instead of 255, if your input image is logical (max pixel range is 1 ) or your image is uint8 then you should use maximum of image pixel range is 255.

Hi,
PSNR shoud be more than 100. Please find max value from your output image and use it as below
psnr= 10.0* (log10((max(max(output_img))/sqrt(mse)));
