|One line summary|| A wrapper around Perceptual Diff Image Comparison tool to compare images, possible issues may be detected if the results are not sufficiently close.
|Detailed description|| Simple wrapper script which walks through a folder and compares each image using Perceptual Image Diff which emulates the way a human looks at an image.
It uses a treshold of number of pixels that are allowed to be different.
Consult the Perceptual Image Diff webpage for more in-depth information about this technology.
The tool reports back:
- if images are (almost) the same and reports back the number of different pixels (PASS)
- if images are not the same (FAIL)
- if an error occured (ERROR)

|Group Evaluation Notes||
| Detailed Evaluation
|| Possibly a useful tool for first 'quick' scan of duplicates in collections of scans and images.
It is quiet slow on Windows and eating up a lot memory when comparing images which are bigger than 100kB.
CPU is probably not an issue. On Windows it used max 50 percent of CPU power, as reported by taskmanager. This might be a false number, needs further investigation.
