I followed this guy and create my own haarcascade xml file. My data set is about dogs face with 500 possitive img, 200 negative bg, 30 stages, but i cant use it to detect anything, tried about 50 different img and no result.
Here is my haar trained file format, is there anything wrong? Or because of my dataset so small? I found its format is different with haarcascade_frontalface_alt.xml file.
