Another command line visual (perceptual) image duplicate finder
Usage of ./imgdup2go:
-algo string
algorithm for image hashing fmiq|avg|diff (default "avg")
-dryrun
only print found matches
-path string
the path to search the images (default ".")
-sensitivity int
the sensitivity treshold (the lower, the better the match (can be negative)) - fmiq algorithm only
-undo
restore removed duplicates
Upon running imgdup2go will create a duplicates directory where it will put the found duplicate files with an informative prefix, eg:
7563e__GONE__image1.jpg
7563e__KEPT__image92.jpg
f469b__GONE__image16.jpg
f469b__KEPT__image19.jpg
The initial hash pairs the files together, the KEPT files were copied from the initial directory while the GONE files were moved.
After inspecting the pairs, if you agree with what the tool found as duplicates you can just remove the duplicates folder; otherwise, move the specific GONE files back into the original directory, removing the prefix. To undo everything you can use the -undo flag.
The algorithms can be switched using -algo flag, in my test I found avg (default) to provide the best results.
For fmqi (Fast Multiresolution Image Querying) you can detect more loosely similar images by increasing the sensitivity, to make it even stricter you can go negative. Enjoy!

From source:
go get -u -v github.com/rif/imgdup2go
The heavy lifting is done by imgsim and duplo libraries. You can find more info on the hashing algorithms at the libraries home page.
A python version can be found here
This tool moves and deletes files. Please make a backup of your image collection before using it!
