I want to understand effects of mean filter in zro mean gaussian noised image with different window size. image is read by imread and assigned to matrix.Although pixel values in the image matrix are between 0 and 255, imshow(uint8(imageMatrix)) and imshow(int8(imageMatrix)) gives different results-in int8 case the image is brighter for example.Why can be this happen, what is the reason and I am not sure which one is true while examining the effects of mean filter on zero-mean gaussian variance noised image? Thanks in advance friends.
MATLAB: Imshow(uint8(imagematrix)) and imshow(int8(imagematrix)) gives different results although pixel values are between 0-255
