[Digikam-devel] People tagging design

[Alex Jironkin]

Is the dedicated icon view the separate tab that Michael was talking about earlier? As an addition to that you should be able to drag and drop tagged face/name from icon view to a tagged region in an image.

After recognition and detection how are tags/regions displayed in a photo? Are the actual tags (Bob, Alice, unknown) only displayed in photo/icon view/both?

Also I guess no meta data will be written until tag is approved, as you don;t want to be re writing tag every time something changes. Which means that there needs to be some temporary tag save location in digikam. Is that going to fit in the new config table in database?
