Also be aware that some people are not fans because it is a KDE project that doesn't integrate totally with other desktop environments and it tries to be an all in one application with image download, catalogue / keywording, RAW development, image maniplation and more included. Though the generation of the 'signature's' and cross checking of them on a large number of images can be a slow process.

This technique has three implementations in digiKam.

The less numerical difference there is between any two image signatures, the more they resemble each other. (It also has an advanced setting allowing multiple boolean searches)ĭigiKam characterizes every image by a lengthy number using a special technique (Haar algorithm) that makes it possible to compare images by comparing this calculated signature. For instance, you can enter the string 'birthday' to search the complete database for occurrences of the word 'birthday' in all metadata text fields, or '05.png' to search for a specific image file name '05.png' (no escaping as in regexpressions needed). You can enter any arguments in the Search: text field and it will be used to determine the results. Quick Search is the adaptive search box at the top of the search dialog (Left Sidebar) and provides you with a simple means to search the digiKam database with a single query. With the three buttons in the top right corner you can choose between a simple list of the saved versions, a tree view and a combined list that shows the versions together with the actions performed with the selected photograph. The Versions tab shows the history and the saved versions of a photograph. In the Excel file generated in this way, duplicates are listed among each other and can be filtered via the SPARETECH ID. Digikam (linux, windows and mac) has a sidebar titled versions For the downstream process of duplicate cleanup, the new duplicate groups are downloaded from the central master data team via the SPARTECH app.
