1. A method comprising: capturing a first image comprising a plurality of pixel intensities; generating a region set of pixel intensities of the first image comprising a subset of the pixel intensities of the first image; generating a delta image comprising a plurality of differences in intensity comprising a difference in intensity between each pixel intensity of the region set of pixel intensities of the first image and each pixel intensity of a corresponding region set of pixel intensities of a subsequent second image comprising a plurality of pixel intensities corresponding to the plurality of pixel intensities of the first image; and visually rendering, for a subsequent comparison, an integrated delta image comprising a second plurality of differences, the second plurality of differences comprising the differences between the plurality of differences of the delta image and the subsequent plurality of differences of the delta image and the subsequent plurality of differences of the subsequent delta image.
