Hello, after testing some different picture managing programs I found that Digikam is a really superb application. However, I think it would be nice if duplicates could be found in the importing process. It should be avoided to add duplicates to the collection rather than searching for duplicates in already imported material. Especially if pictures are shared with friends or copied to an importing directory manually, the applictaion doesn't recognise the pictures as already known. Maybe the already existing duplicates function can be integrated into the import function with an option to not import duplicates.
Hello, I agree that it should be avoided to import duplicate pictures. But even if a similarity threshold of 100% is used, the images do not need to be fully identical. In some cases, the metadata of the pictures may be different. In this case, it is hard to decide for an algorithm if the image should be imported. Any other opinions?
Well, typical use cases, where this kind of process must be disabled : high speed shot sequence while sport events (for ex). With my camera for ex (Sony A77), i can take 12 img/s. Photos are very very similar. I'm sure that algorithm will detect all images as duplicates. And it's normal. For this workflow, i sort myself the items in Light table. I select the best one based on composition, movements, subjects place, etc. In other word, this can pre process while download must be disabled easily in GUI. Gilles Caulier
I agree with the Multishot issue, but I'm still looking for that feature: when migrating all images to a nice and sorted digikam library I often do not know if the old SD card I found during cleanup or the old external backupdrive contain some images that are not already in the library. So I would appreciate this as an optional feature, adding it in the context menu "Download New images (duplicate check)" Maybe an additional step for checking which images will be imported and which not would be helpful to review the process.
