Thank you Dennis, you provided us a collection of 40 males each 10 pics (100×100 pixels).
He wrote in its comments “Now I get much much better results. I thought I share the pics and csv file with you (csv with that many pics is quite some work).Oh, the csv file has only 50 pics, the facerec software could not handle 400 of them. I works nicely with 50. You have to edit the cpp file, I changed lise in “others” and display a text “unidentified other male person”. Enjoy!”
