A lot of applications are available on the market and claim to be able to find similar and duplicate images. Most of those applications are just variations of standard byte-to-byte duplicate finders that can find only 100% identical files.
We did some performance tests choosing only the applications that can find similar images besides finding duplicates. We tested the applications on AMD X2 5000+, 2GB RAM which is an average machine, and scanned 5000 files as some of the applications could not handle large volumes.
The results that we achieved varied.
A nice surprise was the application at the top of the list which is our choice in this review. Besides the performance Visual Similarity Duplicate Image Finder gave accurate results and did not have issues with large volumes of images. It also has a corporate version that is used in online stock photography web sites – we are not surprised by that fact as it managed to scan 50 000 images in several minutes. The PRO version also provides support for 300+ RAW camera image formats.
