Duplicate images often find their way into collections, even commercial stock collections. Now you can clean them of duplicates and near duplicates.
Search a folder (including subfolders) for duplicate and near duplicate images. Match all images or restrict match to same size or same aspect ratio.
Dup Detector creates a data file by opening and reading image pixel data for each image in your collection. It then finds duplicates by % match and displays matching pairs from a log file. You may delete a duplicate at any time.
