A system, method, and machine-readable storage medium for detecting changes in images are provided herein. The system includes an original grid and an image detection software program. The original grid represents an original image. The image detection software program detects changes between the original image and the processed image as follows: receiving a description of the original grid, the processed image and a set of tolerance parameters; scanning horizontally the pixels of the processed image into horizontal runs, scanning vertically the pixels of the processed image into vertical runs, and saving each of the plurality of vertical and horizontal coordinates within the predefined vertical and horizontal tolerance; determining a plurality of processed intersection coordinates; comparing a portion of the plurality of processed intersection coordinates to a portion of the plurality of original grid line intersection coordinates; and providing an image comparison result.
