--- Comment #7 from caulier.gil...@gmail.com --- Nghia, I can clarify one point here : the XMP metadata standard used to store face tags information in image or sidecar. this can be not relevant of Clarifai.com web service of course, but at least this is how digiKam store these metadata in XMP container. Code using Exiv2 shared library to deal with XMP face tags are here : https://invent.kde.org/kde/digikam/-/blob/master/core/libs/metadataengine/dmetadata/dmetadata_faces.cpp Metadata Working Group Region Schema describe the tags list used to identify the interest regions on images : https://www.exiv2.org/tags-xmp-mwg-rs.html This Exiv2 definitions are used in digiKam to play with face tags 5libexiv2 is a C++ component). Exiftool also support MWG-RS, but doc is less readable : https://exiftool.org/TagNames/MWG.html#Regions VoilĂ Gilles Note : digiKAm do not use at all Exiftool, as it's a Perl script CLI. -- You are receiving this mail because: You are watching all bug changes.
