It does not by any error , windows tells me only that the program has stop working. Without any errors.

I resolve this problem, i write the error name. Now it's work but when i run it the dos windows exit with error.

i try to training a classifier, i have create a file .vec whit create sample and it's ok.

Info file name: C:\OpenCV\positive.txt
Img file name: (NULL)
Vec file name: C:\OpenCV\sample.vec
BG  file name: (NULL)
Num: 20
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: 50
Height: 50
Create training samples from images collection...
Done. Created 20 samples

and now use training.bat, this is the file:

C:\OpenCV\opencv-2_4\build\x86\vc10\bin\opencv_traincascade.exe -data classifier -vec "C:\OpenCV\samples.vec" -bg "C:\OpenCV\negative.txt" -npos 20 -nneg 16 -numStages 4 -minHitRate 0.999 -maxFalseAllarmRate 0.5 -w 74 -h 100 -mode ALL -precalcvalBuffSize 256 -precalcdxBufSize 256

But when i call training.bat in dos give me this error:

Image reader can not be created from -vec C:\OpenCV\samples.vec and -bg C:\OpenCV\negative.txt.

Can someone help me please?

ah sorry, i add the path and it's the same: Image reader can not be created from -vec C:\OpenCV\samples.vec and -bg C:\OpenCV\negative.txt. You are right, it's only for understand how work and if it's work, i have try to decrease the num of stages to 10 by 1. The next step it's increase the num of positive and negative image!

Me too, the path in the file negativeNew (for ex C:\OpenCV\image\negative\nameOfImage.bmp) and the vec file contains only numbers. Can the image create problem? I take only a image with signal, (like this: http://www.smalteriaemiliana.it/wp-co... convert in bmp).

I control the file negativeNew.txt and the path it's correct, even files in the same folder.

Hi, I'm new of Opencv and i make a road signal detection and i wanna trainig the algorithm for detect this. I have follow this guide on youtube https://www.youtube.com/watch?v=KFC6j... but in the end they give me an error. this is the file traning.bat

opencv_traincascade.exe -data classifier -vec samples.vec -bg negativeNew.txt -numStages 10 -minHitRate 0.999 -maxFalseAllarmRate 0.5 -numPos 12 -numNeg 1 -w 20 -h 20 -mode ALL -precalcvalBuffSize 256 -precalcdxBufSize 256

And this is the error:

Image reader can not be created from -vec samples.vec and -bg negativeNew.txt.

What I know it would take many more pictures but this is a begin, just for try. Can someone help me with this error? Thanks.
