Abstract
Comparing a sample image to a reference image. Differences between the color channel values of the pixels in the sample image and the corresponding color channel values for the corresponding pixels in the reference image are calculated and compared to predefined tolerances. Based on the comparisons, a pixel status for the pixels in the sample image is defined. An image status indicating whether the sample image differs from the reference image is defined based on the defined pixel status.
