2014-02-18 09:17:23 -0600 asked a question Binary compatibility break

i'm trying to execute a code (application using cuda5.5 and openCV) using QT5.2.0 on ubuntu13.10. It compiles normally but when i execute the code i have the following error message

QMetaType::registerType: Binary compatibility break -- Size mismatch for type 'QPaintBufferCacheEntry' [1024]. Previously registered size 0, now registering size 16. The program has unexpectedly finished.

I don't see where the problem comes from and don't know how to solve it. I've been trying to see where the error comes from. I'm using a Graphical User Interface (GUI) in my project and when i just use an OpenCV function (for example simply to read an image) this error occurs. Meanwhile when i use the same function to read an image in a simple project (not using a GUI) i don't have the error. So i'm wandering if this type of error is related to a GUI and how is it related to a QMetaType::registerType . Any help will be welcome.

my image is loaded correctly after checking

Hi. the output of the CPU and the GPU are differents, GPUCV output matrice is full of zeros and i don't understand where my error comes from while using the gpu calcHist

This's the CPU code

selectedImage1 = image;

vector<Mat> bgr_planes1;

split (selectedImage1, bgr_planes1);

int histSize1 = 256;

float range1[] = {0, 256};

const float* histRange1 = {range1};

bool uniform = true; bool accumulate = false;

cv::calcHist(&bgr_planes1[0], 1, 0, Mat(), b_hist1, 1, &histSize1, &histRange1, uniform, accumulate);

cv::calcHist(&bgr_planes1[1], 1, 0, Mat(), g_hist1, 1, &histSize1, &histRange1, uniform, accumulate);

cv::calcHist(&bgr_planes1[2], 1, 0, Mat(), r_hist1, 1, &histSize1, &histRange1, uniform, accumulate);

Thx for helping

i'm trying to compare the computation of histogram on cpu and gpu using gpucv but there's something i don't understand. The results are differents and i don't understand why. this is the code i'm using for gpucv

cv::Mat histImage;

histImage = cvLoadImage(img.toStdString().c_str(), CV_8UC1);

gpu::GpuMat devImage, result;


gpu::calcHist(devImage, result);

Thanks for helping
