Question

I am trying to store a IPL_DEPTH_8U, 3 channel image into an array so that I can store 100 images in memory.

To initialise my 4D array I used the following code (rows,cols,channel,stored):

int size[] = { 324, 576, 3, 100 };
CvMatND* cvImageBucket; = cvCreateMatND(3, size, CV_8U);

I then created a matrix and converted the image into the matrix

CvMat *matImage = cvCreateMat(Image->height,Image->width,CV_8UC3 );
cvConvert(Image, matImage );

How would I / access the CvMatND to copy the CvMat into it at the position of stored?

e.g. cvImageBucket(:,:,:,0) = matImage; // copied first image into array

You’ve tagged this as both C and C++. If you want to work in C++, you could use the (in my opinion) simpler cv::Mat structure to store each of the images, and then use these to populate a vector with all the images.

For example:

std::vector<cv::Mat> imageVector;
cv::Mat newImage;

newImage = getImage();       // where getImage() returns the next image,
                             // or an empty cv::Mat() if there are no more images
while (!newImage.empty())
{
    // Add image to vector
    imageVector.push_back(image);

    // get next image
    newImage = getImage();
}
