Re: [Imtoolkit-users] Comparing 2 images

[Antonio S. <sc...@te...>]

  First, you compute the image that has the difference between the two
images:

im.ProcessArithmeticOp(src_image1, src_image2, dst_image, im.*BIN_DIFF*)

  Then you can check the statistic of the result image:

stats = im.CalcHistogramStatistics(dst_image)

  You can use stats.mean or stats.positive

------------------------------------------------------------------

 Another option is to use the RMS error between two images:

rms = im.CalcRMSError(image1, image2)

  It is a single value that you can for two identical images is zero.

Best,
Scuri
