Loading large images - OpenCV Error: Insufficient memory

edit

Hello all,

I am trying to read a large image in OpenCV & Qt 5.7 (32bit). This is the code I'm running:

#include <opencv2/opencv.hpp>

using namespace cv;

int main(int argc, char *argv[]){

    Mat mat = imread("C://Users//Z//Documents//test//3_dsm_ortho//2_mosaic//test_transparent_mosaic_group1.tif");
    return 0;
}

When I run it, I get the following error:

OpenCV Error: Insufficient memory (Failed to allocate 1116737892 bytes) in OutOfMemoryError

How can I read large images in OpenCV?

Bellow are additional information about my image & PC.
