I am new in DSP.
I am currently working with a project and I want to try which algorithm works better given different image noises.
To test it out, I have been using the Gaussian noise in images.
I have been using this equation for
f = imnoise(im,'Gaussian',0,0.001)
And then increasing by 0.001 and testing. As can be seen, I am using zero-mean noise. Is this the right approach to test the algorithm on different noises by changing the variance, or should I just change the mean?
