digiKam 5.2.0 Changelog

  • This release introduce also a new red eyes tool which automatize the red-eyes effect reduction process. Faces detection is processed on whole image and a new algorithm written by a Google Summer of Code 2016 student named Omar Amin is dedicated to recognize shapes and try to found eyes with direct flash reflection on retina.
  • This new tool is available in Image Editor and also in Batch Queue Manager to be able to process a set of photos at the same time. The algorithm have been very optimized for speed efficiency and for small memory fingerprint. End user can adjust just a single parameter about the reducing level of retina red color to the average of blue and green channels. The default threshold have been tested successfully with a trial and error basis from a large data-set of images. So typically, no user interaction are need with this new version of this tool compared to older one, where no red eyes detection was performed, and a lots of manual settings was required to process this kind of correction.
