I am getting this list as an output
[268541.0, 264014.0, 324155.0]
Actually in my code i am finding difference between two images and i need to
count the number of pixels which appear as a difference of these two images.
These values i m getting as output are little large.
i m pasting my code again....
file1=Image.open("./pics/original.jpg")
file2=Image.open(val)
diff = ImageChops.subtract(file1,file2,0.3)
stat1 = ImageStat.Stat(diff)
count1=stat1.sum
print count1
diff.save("./pics/diff"+".jpg")
diff.show()
AS you can see i am finding difference of two images which are nearly
identical. But they have some pixels that are different and i can see that
in the output image diff.jpg. So i am trying to put this difference image in
the imagestat and trying to see if i can get to count the number of pixels
.......
thanks,
