I took my matrix from Matlab: fspacial('laplacian'); alpha = p2; alpha = max(0,min(alpha,1)); h1 = alpha/(alpha

Its symmetrical (and try it anyway same answer :) )

Yes I need convolution its default option as my imfilter function is: ILAP = imfilter(lm, h, 'replicate', 'conv'); Wh

Laplace matlab opencv differences Hello I wanted to implement the imfilter with the Laplace option (Sobel option worked

Hello In my image I detect the blue line (through blobs) make a close rectangle on the blob take the bottom of the rectangle and split the image to the top and bottom half over my red line(sorry it is not a straight line). But my problem is how can I extract the part of the image on top of the blue line with the most of area taken (where I drew the red line (obviously I don't know exactly if I took the most area but that is the general idea)

THANKS!!!😀 IT WORKS I did the first two steps located the line but it never accured to me to do an inverse image and loo

The area above the blue line with a curve has water in it. The area below the blue line does not have water thus you see

It is for work interview what I need to do is fft on all the pixels in the frame on like all 1st pixels fft signal all 2nd pixels fft signals and I cannot make a matrix of olumns of every picture I use the latest version of opencv downloaded from your site

Hello I have the following code attached

using namespace std;
using namespace cv;
int main()
{
CvCapture *capture=cvCaptureFromFile("C:\\test.mp4");
static const int length =  (int) cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_COUNT); //250
static const int width  =  (int) cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_WIDTH); //480
static const int height =  (int) cvGetCaptureProperty(capture, CV_CAP_PROP_FRAME_HEIGHT); //360
static const int fps    =  (int) cvGetCaptureProperty(capture, CV_CAP_PROP_FPS);
Mat image;
Mat image_split[3];
Mat image_new;
Mat image_temp;
Mat image_vec = (Mat_<int>(1, width*height) << 0);
//Mat A = (Mat_<int>(length, width*height) << 0);
Mat A[length];
Mat B;

IplImage* frame;

for (int i = 0; i < length; i++)
{
    frame = cvQueryFrame(capture);

    if (!frame)
    {
        break;
    }
    image = cvarrToMat(frame);
    split(image,image_split);
    image_new = image_split[2];
    image_vec = image_new.reshape(1, height*width);
    image_vec.copyTo(A[i]);
}


cvReleaseCapture(&capture);
return 0;}

and my problem is that I need to put image_vec into 2d matrix A and not create a multi-dimensional matrix what I tried to do is image_vec.col(0).copyTo(A.col(i)); and for some reason it didn't work thanks
