Import XMP face regions

Describe the feature you'd like to request

I have a large number of images (tens of thousands) that I have tagged with face regions. This has involved countless hours using automated tools (such as Adobe Lightroom, Digikam, Picasa, etc) and performing manual adjustments, additions and corrections.

I would like to be able to import existing XMP face regions from these images into Recognize.

Note that one could leverage these existing regions to facilitate training for Recognize.

Describe the solution you'd like

A command line and/or UI function would import existing XMF face regions into the Recognize database, and run training for each of the individuals and their associated regions.

MVP

• Import MWG XMP face regions (used by all of the above common tools), overwriting any existing face regions.

Possible Extended Features:

• Merge XMP regions with existing face regions by name. Imported duplicate face regions in a given image can be either ignored or can replace the existing region (user option).
• Re-import changed XMP region information and update corresponding image information in Recognize.
• Support other face region standards.
• Specify name or names of persons to import

Describe alternatives you've considered

Re-tagging faces using Recognize: This is very undesirable, as it wastes a tremendous amount of prior work, as well as wasting valuable verified face correlations.

No files, tests, or entry points are named. Start by locating the existing face-region import, database, and training entry points, then determine how MWG XMP regions are represented and how names map to individuals. Done means the MVP imports MWG regions, overwrites existing regions, and trains the associated individuals.
