Pytanie 17
Image equalization
mapping which reassigns the intensity values of pixels in the input image such that the output image contains various distribution of intensities
non-linear mapping which reassigns the intensity values of pixels in the input image such that the output image contains a uniform distribution of intensities
mapping which reassigns the intensity values of pixels in the input image such that the output image contains values of intensities equaled to 256
mapping which reassigns the intensity values of pixels in the input image such that the output image contatins the same values of intensities
