PerceptualDiff Description
PerceptualDiff was desighned to be an image comparison utility that makes use of a computational model of the human visual system to compare two images. Usage perceptualdiff image1.(tif | png) image2.(tif | png) - verbose : Turns on verbose mode - fov deg: field of view, deg, in degrees. Usually between 10.0 to 85.0. This controls how much of the screen the oberserver is seeing. Front row of a theatre has a field of view of around 25 degrees. Back row has a field of view of around 60 degrees. - threshold p : Sets the number of pixels, p, to reject. For example if p is 100, then the test fails if 100 or more pixels are perceptably different. - gamma g : The gamma to use to convert to RGB linear space. Default is 2.2 - luminance l: The luminance of the display the observer is seeing. Default is 100 candela per meter squared - output foo.ppm : Saves the difference image to foo.ppm
