Ah, found this one (again, looked at it in the past too): http://www.lac.inpe.br/JIPCookbook/6050-howto-compareimages.jsp Now... what that algorithm is doing is probably quite a bit over the board. If for example the only change is the zoom level I don't want the algorithm to tell me the images are similar enough... I just want the tool to tell me if a human would spot a difference... My concern is would be moving from the past tool that required the two images to be pixel by pixel identical, which failed, to one that would not spot obvious differences... which would also fail Cheers Andrea -- ------------------------------------------------------- Ing.
