Pixel Comparison

Abstract: a first pixel in a first group of neighbouring pixels classified as acceptable or not acceptable with respect to a second pixel in a second group of neighbouring pixels. it is determined whether a difference between the first pixel and the second pixel is greater than a threshold difference, and in response to determining that the difference between the first pixel and the second pixel is greater than the threshold difference, the pixels in at least one of the first and second groups of neighbouring pixels are analysed to determine whether the difference is indicative of the first pixel being erroneous. the first pixel is classified as acceptable or not acceptable based on whether the difference is determined to be indicative of the first pixel being erroneous, and the classification of the first pixel is outputted.
