一些設定posNum要注意的問題

http://stackoverflow.com/questions/10863560/haar-training-opencv-assertion-failed

vec-file has to contain >= (numPos + (numStages-1) x (1 - minHitRate) x numPos) + S S: count of samples from vec-file that can be recognized as background right away (num bg image in background file descriptor)

Other tips

  1. 背景不要用白的
  2. HAAS會比LBP慢很多
