face detection 1.5 vs 2.1

I used a KS board and tried the face detection example before updating to 2.1
It worked well and drew box around detected face

Then I updated to 2.1 - did not erase the filesystem
Now when I run the same face detection example - it can’t find my face. Same lighting conditions.
Do I need to copy the haar files somehow or ???

Only 1 major change since 1.5, this code doesn’t get updated too much, I’ll test the old version and see if there’s a problem.

Okay so that one change is a check to skip regions that doesn’t have too much contrast, could you try



That’s working so much better - thanks for the tip. So many things to try.
