Right now, i am doing a research on how the Butterworth filter can reduce the noise in images captured by digital camera. For start, what i need is images which contain noise in it. My question is;
Is there is a way to add artificial noise such as gaussian noise into images?
After i have an images with noise in it, what are the parameters that i should have to create butterworth lowpass filter?
This is my block diagram of my research. any help will do:
