Version
7.0.0 of the digiKam photo editing and management application is out.
This release adds support for a number of new raw formats, support for
Apple’s HEIF format, and a new mosaic plugin. The headline feature,
though, appears to be completely reworked face detection: “The new
code, based on recent Deep Neural Network features from the OpenCV library,
uses neuronal networks with pre-learned data models dedicated for the Face
Management. No learning stage is required to perform face detection and
recognition. We have saved coding time, run-time speed, and a improved the
success rate which reaches 97% of true positives. Another advantage is that
it is able to detect non-human faces, such as those of dogs.“
