5D blob in opencv : back to c function? #25129
Description
Describe the feature and motivation
I need a 5D blob as model input : tensor: float32[2,1,3,240,320]
I cannot find an opencv function. i wrote :
Mat img0 = imread("C:/data/kitti/testing/image_2/000198_10.png");
Mat img1 = imread("C:/data/kitti/testing/image_2/000198_11.png");
Image2BlobParams param;
param.datalayout = DNN_LAYOUT_NCHW;
param.size = Size(320, 240);
Mat blob0 = blobFromImageWithParams(img0, param);
Mat blob1 = blobFromImageWithParams(img1, param);
vector<int> szData = { 2, 1, 3, 240 ,320 };
Mat blob(szData, CV_32FC1);
memcpy(blob0.data, blob.data, 3 * 240 * 320 * 4);
memcpy(blob1.data, blob.data + 3 * 240 * 320 * 4, 3 * 240 * 320 * 4);
May be an opencv function would be usefull.
As a problem never comes alone output result is tensor x: float32[1,2,240,320]
It would be nice to have an opencv function which can extract two images x[0,0] and x[0, 1] (#24173)
