How to scale an 640x480 pixels down to 8x4 pixels?

The same as what they did in here: image description

Image 1 is 640x480 pixels and then they scaled it down to 8x4 pixels.

Note: I am new to OpenCV.

does OpenCV has a function capable of doing this? I'd been reading about the Geometric Image Transformations in OpenCV.

In c++, the function is called cv::resize. Have a look at the documentation here.

does the resize function will produce the same result as the Image 2?
