Digikam has powerfull search funtcion, which finds duplicates in albums. Nice feature to have would be to *do* something after the search with the images. The most obvious action could be: delete the duplicates, but the list could go on to different scenarios.
This is the real example which occured after I have imported from the mobile camera 1000 photos which could be imported previously, a years ago. They have different file names of course, so from filesystem point of view they are different. I would like to clean my albums, but in automated way and wonder what is possible.
Seems a bit difficult to me. How can an automated process decide which one of two identical images to process (delete or whatever)? Of course you could set the threshold to 100% and then say it doesn't matter, just process one of them. But 1. your search result gets very small with 100% and 2. the process would still need a rule to decide and that will most likely not match everybody's needs.
