Witryna16 lut 2024 · Assuming it's quantization, and you're willing to alter the actual initial data, you can find the quantization delta, then make a noise image that's plus or minus that amount, and add it in. For example if there are gray levels only at 0, 10, 20, etc. you can make a noise image and add it in. Witryna[28] Y. Kalantidis, Y.
