  1. The bug of traincascade is that it had assert() in such cases, but it has to throw an exception with error message for a user.
  2. Is space piracy orbitally practical?
  3. However, somehow the eof never occurs (at my place, a mac using macports) before the assert is being thrown.I already added a null char to the end of my .vec file
  4. It may be of some help.
  5. And it works perfectly here on Ubuntu 14.04 AND Windows 7 / 8.1.

 opencv_traincascade -data data -ve... So, if you generated a .vec file (with the createsamples.exe utility) with, lets say, 500 positive samples, you must call haartraining.exe with input parameter -npos 450 (for example). Mergevec isn't officially part of the OpenCV branch, not in 2.4 branch not in master branch. The .txt file containing the positive samples looks something like this : picture1.pgm 1 0 0 48 96 meaning that there is 1 positive sample in picture 1 from (0,0) to
