how to reshape a mat like (1,3,height,width) to (height,width,3)?

edit

how to initial cv::OutputArrayOfArrays result? I tried this code

  std::vector<std::vector<cv::Point>>  result;
    cv::dnn::imagesFromBlob(out, result);

it still failed

I tried

std::vector<std::vector<cv::Mat >> vectorOfImages;
cv::dnn::imagesFromBlob(out, vectorOfImages);
 but  the  size of vectorOfimages is only [1,height,width]

@lunasdejavu, Cannot reproduce. Here is my script:

import cv2 as cv
import numpy as np

batch_size = 16
blob = np.random.standard_normal([batch_size, 3, 44, 55]).astype(np.float32)
images = cv.dnn.imagesFromBlob(blob)
print(len(images))
print(images[0].shape)

which gives

16
(44, 55, 3)

So 16 images with 3 channels and 55 width, 44 height.
