Hi everyone,
I have spent the past 3 or so hours trying to figure out what is wrong with my introductory attempts at getting haar cascades to detect facial features. I am just beginning to explore this topic so I am essentially just running the example code found here
http://docs.opencv.org/doc/tutorials/objdetect/cascade_classifier/cascade_classifier.html#cascade-classifier
The problem is it doesn't detect my face or eyes! I have tried a few different cascades and the only one that detected anything was the lbpcascade_frontalface. Other than that I am getting zero results. Are these haar cascades highly unreliable or am I (more likely) doing something wrong in my code? My code is exactly what is found in the example.
Would love any thoughts people have and/or pointing me in the direction of basic examples of haar cascades would be helpful - it's very hard to find anything beyond the example I posted above.
The .xml files are in the correct place (as I mentioned I AM getting results for one lbpcascade) so I don't believe that is the problem.
Thanks!
