Transform cannot enroll all TemplateList objects about openbr

[jklontz]

This is the expected behavior. When enrollAll is true, the system will only enroll the faces it correctly detects, which in many cases is less than the total number of images. This is generally the desired behavior in most practical applications.

The alternative is when enrollAll is false. In this case the system will enroll exactly one face per image no matter what (even if it fails to detect a face!). This is generally the desired behavior in most research scenarios.

enrollAll is a terrible name that needs to be changed to something else. But i suspect that is the source of the confusion?

Sounds like this is not the case. Because all of them are valid faces and they can be compared one by one.

Hmm, how do you do the 1-to-1 comparison? enrollAll is false by default, so I still think this is the problem. Perhaps you can post a minimum reproducing example with images to the mailing list?

They might be different issues. The issue I noticed was in the face_recognition_search example code as follows:

10 // Enroll templates
11 br::Globals->enrollAll = true; // Enroll 0 or more faces per image
12 target >> *transform;
13 br::Globals->enrollAll = false; // Enroll exactly one face per image
14 query >> *transform;

I have 10 images loaded in target. But after the above line 12, the target has only 6 images. So the workaround would have to enroll the target images one by one like the above line 14.

Any comments?

Why not just delete line 11 and have enrollAll = false?

It works. Can you explain a little what the enrolling does? As you know, the target is br::TemplateList. How can it work for enrolling one only?

Originally I used a loop to enroll them one by one like

for (i = 0; i < target.size(); i++)
{
target[i] >> *transform;
score[i] = distance->compare(target[i], query);
}

Happy to explain, but can you re-ask this on the mailing list so that it's more visible to others who may be wondering the same thing?

Just posted but it is weird it cannot showup immediately.
