title: Opencv haartraining stuck at stage 0
body: <p>I am trying to detect a picture if it has a cat in image or not ,the size is just original picture size and when I do</p>
  
  <pre><code>opencv_haartraining.exe -data D:\meitu\res\data -vec D:\meitu\res\pos.vec -bg D:\meitu\recordfail\bg.txt -npos 110 -nneg 147 -nsplits 2 -mem 512 -nonsym -w 974 -h 1047 -minpos 100 -nstages 4
  </code></pre>
  
  <p>it just stays in stage 0 forever, I also tested opencv_traincascade however it just crash .</p>
  
  <p>I wonder how do I solve this? I did some google saying opencv can't handle image over 100x100 , if this is the case, does it means I have to manually crop all image to just train the cat instead of the whole image?</p>
  
  <p>original vec generation code</p>
  
  <pre><code>opencv_createsamples.exe -info D:\meitu\recordok\info.txt -vec D:\meitu\res\pos.vec -num 110 -w 974  -h 1047
  </code></pre>
