This is the same question of mine for StackOverFlow.

I am making a cascade detecter with OpenCV. But opencv_traincascade.exe does not run. How can I fix this problem?

Bellow is the composition of the folder for using a making detecter. Desktop --cv ----cascade_detecter ----negative_image ------neg1.png ------neg2.png ------neg3.png ------(total: 265 data) ----positive_image ------pos1.png ------pos2.png ------pos3.png ------(total: 257 data) ----annotations.txt ----bg.txt ----opencv_annotation.exe ----opencv_createsamples.exe ----opencv_traincascade.exe ----opencv_world346.dll ----positive.vec

annotations.txt was made by opencv_annotation.exe and it is bellow. positive_image\pos1.png 1 578 245 160 91 positive_image\pos2.png 1 552 258 150 80 positive_image\pos3.png 1 489 286 172 68 (total: 257 data)

bg.txt is bellow. .\negative_image\neg1.png .\negative_image\neg2.png .\negative_image\neg3.png (total: 265 data)

I ran following command in the cv folder with PowerShell.

.\opencv_traincascade -data .\cascade_detecter\ -vec .\positive.vec -bg .\bg.txt -numPos 231 -numNeg 265 --featureType HAAR -mode ALL

Then, the application returned following error

POS count : consumed 231 : 231 Train dataset for temp stage can not be filled. Branch training terminated. Cascade classifier can't be trained. Check the used training parameters.

you're trying to do this with 3 positive images only ? won't work.
