OpenCV - TranCascade error (bad_alloc) - c++

Question

I've got a problem training the cascade classifier.
First, I create samples using opencv_createsamples:
./opencv_createsamples -vec test.vec -img ./positive/speed_50.jpeg -bg /home/boris/src/cascade/neg.txt -num 50 -w 150 -h 150
It works nice, and the output is following:
Info file name: (NULL)
Img file name: ./positive/speed_50.jpeg
Vec file name: test.vec
BG file name: /home/boris/src/cascade/neg.txt
Num: 50
BG color: 0
BG threshold: 80
Invert: FALSE
Max intensity deviation: 40
Max x angle: 1.1
Max y angle: 1.1
Max z angle: 0.5
Show samples: FALSE
Width: 150
Height: 150
Create training samples from single image applying distortions...
Done
Then the cascade trainer:
./opencv_traincascade -data /home/boris/src/cascade -vec ./test.vec -bg ./neg.txt -numPos 50 -numNeg 2 -w 150 -h 150
And I get the following error:
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Emergency stop (core dumped)
neg.txt file:
img/img1.jpeg
img/img2.jpeg
both files exist in the img directory.
OpenCV version is 2.4.2, OS is Ubuntu 12.04.
Thanks for any help.

Answer 1

you need to set w and h to the same size than the sample generated, 150 in your case. I am having he same problem for any sample size too big. It works for 48x48 not for 96x96. Let me know if you sloved the problem with bigger samples.
