I would like to compare sets of images (a reference and a test image) pixel by pixel.
Specifically, I would like to calculate the absolute difference in grayscale value for each pixel and them sum the values.
For example, something like this…
For all i & j
Sum( ABS(Grayscale Value(Reference Image)i,j - Grayscale Value(test image)i,j))
I want to calculate the “relative error” or degree of how much the test image deviates from a reference image.
If you can’t tell, I don’t know Java and will have to learn it to be able to do this I guess…
What would be the best way to do this?
Is there a plug-in out there all ready that can do this?
