After a year of development release of a program for managing a collection of photos developed by the KDE project. The program provides a comprehensive set of tools for importing, managing, editing and publishing photos, as well as images from digital cameras in raw format. The code is written in C++ using Qt and KDE libraries, and licensed under GPLv2. Installation packages for Linux (AppImage, FlatPak), Windows and macOS.
A key improvement in digiKam 7.0 is a new, completely redesigned face classification system that allows you to detect and recognize faces in photos and automatically tag them accordingly. Instead of the previously used from OpenCV in the new release uses an algorithm based on , which allowed to increase the accuracy of determination from 80% to 97%, increase the speed of work (parallelization of calculations on several CPU cores is supported) and fully automate the process of assigning tags, relieving the user of the need to confirm the correctness of the performed comparison.
The kit includes an already trained model for identifying and matching faces, which does not require additional training - it is enough to tag one face in several photos and the system will be able to identify and tag this face in the future. In addition to human faces, the system can classify animals, and also allows you to determine distorted, blurry, inverted, partially closed faces. In addition, a lot of work has been done to optimize the convenience of working with tags, the matching interface has been expanded, and new face sorting and grouping modes have been added.
Of the improvements not related to face recognition, the addition of support for 40 new RAW image formats is noted, including those used in the Famous Canon CR3, Sony A7R4 (61 megapixels), Canon PowerShot G5 X Mark II, G7 X Mark III, CanonEOS, GoPro Fusion cameras , GoPro HERO* etc. In general, thanks to the use of libraw, the number of supported RAW formats has been increased to . Support has also been improved for the HEIF image format used by Apple to distribute HDR images. Added support for the updated XCF format used in the GIMP 2.10 branch.
Other improvements include:
- Plugin included , which allows you to create images from other photos.
- Added a setting to store location information in the metadata of image files.
- Added settings that define options for storing color labels in metadata.
- The SlideShow tool has been converted into a plug-in for digiKam and Showfoto, and extended with support for random display mode.
- The HTMLGallery plugin implements a new Html5Responsive layout that allows you to generate a photo gallery that adapts to both desktop and smartphone screens. Also, problems with the display of labels and notes in the symbols of national alphabets have been resolved.
