Bug 392007

I have a bunch of bugs, wishes, and possible improvements  to report regarding face detection, face recognition and face tagging, according to has been discussed in several posts in the mailing list. This is one of them. It's based on this post: http://digikam.1695700.n4.nabble.com/digiKam-users-Difference-between-face-tag-and-normal-tag-tc4705362.html

The current management of tags and face tags is very confusing. The two are managed in the same way, and appear intermixed with each other. There is no visible way to tell them apart. Only right clicking on a tag, and checking if the "Mark as face tag" option appears will indicate that it is indeed not a face tag.

For some reason, you can also use a face tag as a regular tag (but no vice versa). 

This leads to some confusing situations:

- What happens if I use an existing face tag for tagging a picture without a face region?. Would it be considered a regular tag for some pictures, and a face tag for others?

- Would renaming or deleting a face tag delete the face region on the picture from the metadata? If not, would it keep a face region without a name?

- Would renaming or deleting a regular tag also affect its face tag?

- If a face tag matches with an existing regular tag in the library, it will "fuse" both tags and show them as one. Will digikam write that name also as a regular tag on the file?



I think it would be much better if tags and face tags were managed separately. Only showing regular tags in the Tag panel, and face tags in the people panel, for instance.

 
At least a small but significant improvement without changing the current behavior would be to show a different icon for face tags and regular tags.
