Listing Microsoft People Tags with no face rectangle associated

[José Oliver-Didier]

In Microsoft's Windows Photo Gallery – People Tags can contain an optional "rectangle" which identifies the person within the photo. Thus, if you run the following exiftool command:

Code Select Expand

exiftool .\190516-1705.JPG -RegionInfoMP -struct -json

the returned result is:

Code Select Expand


[{
  "SourceFile": "./190516-1705.JPG",
  "RegionInfoMP": {
    "Regions": [{
      "PersonDisplayName": "John",
      "Rectangle": "0.554502, 0.164692, 0.063981, 0.095972"
    },{
      "PersonDisplayName": "Alice",
      "Rectangle": "0.324219, 0.180539, 0.064063, 0.097304"
    },{
      "PersonDisplayName": "Mark",
      "Rectangle": "0.456250, 0.273154, 0.058594, 0.087925"
    },{
      "PersonDisplayName": "Abraham"
    }]
  }
}]


In this particular example, Abraham has no Rectangle tag. So my question is - If there is a way using exiftool to list all of the jpg files with People Tags which have no ("rectangle tags") associated?

Something with an output (or similar) such as:

Code Select Expand

190516-1705.JPG Abraham
190516-1706.JPG Mark
190516-1706.JPG Alice
190516-1707.JPG Mark

Note that 190516-1706.JPG has two People Tags which meet this condition.

Here is a config file that will allow you to list all faces without rectangles.  The command could be something like this:

exiftool -config my.config -p "$filename $norectangle" -if "$norectangle" DIR

Code Select Expand

%Image::ExifTool::UserDefined = (
    'Image::ExifTool::Composite' => {
        NoRectangle => {
            Require => 'RegionInfoMP',
            ValueConv => q{
                my @rtn;
                foreach my $region (@{$val[0]{Regions}}) {
                    my $name = $$region{PersonDisplayName} or next;
                    push @rtn, $name unless $$region{Rectangle};
                }
                return undef unless @rtn;
                return join ', ', @rtn;
            },
        },
    },
);

%Image::ExifTool::UserDefined::Options = (
    Struct => 1,
);

1;

Thanks again Phil!

Using your config file I exported the output to a file which aided my analysis.

Code Select Expand

exiftool -config my.config -p "$filename; $norectangle" -if "$norectangle" -r DIR > NoRectangle.txt
