Description:

A True Duplicate / Similar Image Finder.

Just drag and drop any image folders from Finder or events from iPhoto on your local drive onto Unik. Then Unik will start comparing. You can simply add more images whenever you want and detect duplicates. It's that easy.

Unik compares not the binary data but the image contents, so that you can find truly similar images regardless of file types, resolutions, directions and color saturations.

◦ Caching for fast access later
◦ Adjustable similarity threshold
◦ Safe tagging to images from iPhoto
◦ Fast and stable comparison algorithm
◦ Mode for comparing meta data of the files
◦ Search, sort, select and remove images in result
◦ Options for excluding images with low contrast from result
◦ Options for comparing images even flipped, rotated and gray-scaled.

[Info] Comparing images over network or on USB medias needs much time. It is strongly recommended to use images on local hard drive.

Version 1.0.2
Review by G.O. Fry

Awesome just what i was looking for - My hard drive crashed but I was able to extract about 45,000 photos. Most of the photos were duplicates of photos and some photos weren't even photos. From an external drive, I used this app to filter all the photos and brought them down to 19,000 pictures. I had to rescan many times (which wasn't a problem) and I now have 10,000 photos with duplicates. I probably had 6,000 orignally. I found it was best to not use iPhoto for as long as I can with this app. But doing this i've learned alot from this app. PROS: -Works fast -Scans Well -Can scan from different drives -Simple to use -Cheap -If not in iPhoto: -Can find the best quality photo from hundreds of duplicates and delete them in one click. CONS: -No help from help bar or online (they figure the app is already simple enough) -A scanned iPhoto library marks all their duplicates with stars, to delete these duplicates you have to unclick them to make them un-stared, Unik will delete all unstarred photos, but you have to click on these duplicates… ONE AT A TIME (It's annoying and takes forever) This app simply needs a button that says "Unstar all red star photos." If this app were updated with that, it would be a perfect duplicate deleting app. Hope this helps!

iPhoto Previews Gone! - I used this app to delete duplicate iphoto files and it worked well at that but after it left all my iPhoto pics a Blank Dotted Line Square and I have to "Rotate" all the pics(over 3,000) 4x's to get the pic to show back up in iPhoto and be in the correct position. I found out that you can do multiple pictures so it makes it easier getting your iPhoto previews back but it won't let you rotate if you have a Video file in the selected pictures to rotate.

Awesome program… - This program is incredible. After 10 years of collecting photographs it found all kinds of duplicates that even photoshop couldn't detect. Literally saved me hundreds of hours and 10s of gigs of data.

Review by nikonion2000

Works great! - I tried many of the more expensive photo dup finders. None of them worked nearly as well as this simple app for finding duplicate photos. I changed the default settings to 100% match so that I wouldn’t have to worry about which file the app chose to remove. At 100% it only found exact dups. Worked like a charm.

Review by Gump3rs

Life Saver!!! Awesome! - I have a project that I had over 1000 images with duplicates that I reduced the resolution and renamed the file, then accidentally combined them in the same folder. I looked for an app that didn’t just look at the date, meta data, but one that actually compared the image itself, and this was what I needed….. this has saved me days and possibly weeks of sorting. I don’t normally give a review but I could not ignore this app’s help. Thank you!!!!

Review by aliris19

Fab - I don't know the universe of duplicate-identifiers out there but this does a fine job on an absolute basis. You have to play a little bit to really get it primed to erase only those selected, but once you play with the include/exclude star options, you can get there. I like that you can specify percentage similarity because relevance and accuracy will depend on image content to some extent; you can search iteratively. Very useful for me!! I really appreciate this app; thank you. Best two bucks I've spent.
