Hi! I want to use opencv with release mode in VS2012 but I get the mentioned error! I worked with debug mode and it was ok! can anyone help?

Hi, I added an answer. my mistake was the one I mentioned. It worked for me!

take a look at this: http://answers.opencv.org/question/10872/cascade-training-error-opencv-244-train-dataset/

Your number of training examples are small, I think you should provide more training data. instead of 3 use 1000 or more. I had the same problem before I think that fixed in this way!

how many training data do you have?

how many training data do you have?

Thanks, I did it but it didn't work :)

this is the solution and I coulden't accept it as a solution!

The problem solved!

I just compile opencv from source with cmake. and then the problem vanished!

Hi

I just installed the opencv. When I try to import the cv2 I get this error:

  RuntimeError: module compiled against API version 9 but this version of numpy is 7

Then I check the latest release of the numpy and it was 1.7. I installed this version, but the problem yet exist! how can I fix it.

I using python 2.7 on the Window 7(Ultimate)

Hi there! I used createsamples.exe to create my .vec file then I tried to use cascade training according to the OpenCV doc. But I came to this error:

PARAMETERS:

cascadeDirName: CassCade
vecFileName: Positive\ResistorP1.vec
bgFileName: Negative\NegSamples.txt
numPos: 150
numNeg: 150
numStages: 20
precalcValBufSize[Mb] : 1024
precalcIdxBufSize[Mb] : 1024
stageType: BOOST
featureType: LBP
sampleWidth: 24
sampleHeight: 24
boostType: GAB
minHitRate: 0.995
maxFalseAlarmRate: 0.5
weightTrimRate: 0.95
maxDepth: 1
maxWeakCount: 100

===== TRAINING 0-stage =====
<BEGIN
POS count : consumed   150 : 150
Train dataset for temp stage can not be filled. Branch training terminated.
Cascade classifier can't be trained. Check the used training parameters.

I use this command for cascade training:

opencv_traincascaded.exe -data CassCade -vec Positive\ResistorP1.vec -bg N
egative\NegSamples.txt -numPos 150 -numNeg 150 -numStage 30 -featureType LBP -pr
ecalcValBufSize 1024 -precalcIdxBufSize 1024

my .vec size 2.25MB and number of positive samples created by opencv_createsamples.exe is 2000 and number of negative samples is mor than 600 .jpg files.I don't know what's wrong with it ! Thanks in advance! :)

I want to make an augmented reality app. so first of all i trained a cascade classifier for this marker!

image description

I used cascade training on this image and after 2 days! it finished!! so according to the face detection tutorial I followed the steps but when I want to load the "cascade.xml" file it can not open it and exit the program.

specifically in this code:

CascadeClassifier ARMarker;
if(ARMarker.load("cascade.xml"))
{
    cout<<"can not open the file."<<endl;
    exit(1);
}

is there any help!?

Thanks in advance! :)

how should I set that I'm using x32 bit system!? all dlls that corresponds to the release mode is in lib directory. and they correctly added to the path variable!(as I did for debug mode)

Thanks, but i read that article. I am looking for something different.

When I run opencv 2.4.4 I get this error in the run-time. all the configuration set to use opencv in debug mode. OS: winXP

How should I check it? I make a property sheet for the Release mode and added it to the Property Manager under Release part, my settings are : C:\OpenCV 2.4\opencv\build\include C:\OpenCV 2.4\opencv\build\include\opencv C:\OpenCV 2.4\opencv\build\include\opencv2 --- Linker->Additional Libraries: C:\OpenCV 2.4\opencv\build\x86\vc11\lib -- opencv_core244.lib -- Linker -> Input -> additional dependencies: opencv_highgui244.lib opencv_calib3d244.lib opencv_contrib244.lib opencv_features2d244.lib opencv_flann244.lib opencv_imgproc244.lib opencv_legacy244.lib opencv_ml244.lib opencv_nonfree244.lib opencv_objdetect244.lib opencv_photo244.lib opencv_stitching244.lib opencv_ts244.lib opencv_video244.lib opencv_videostap244.lib

---- So i totally confused!

Yes I knew and I did that! I got the same error! it's funny all the things are the same as debug mode but just need to remove a 'd' from the .lib files then it should works! but it didn't!
