Insert a patch (32x32) into an image (256x256), how?

Question

I have a patch with size 32x32 and I have the center coordinate and the x1,y1,x2,y2 coordinates of the patch in the image. I do not know how to add this patch to its position in an image with 256x256?

Answer 1

You can simply use slicing in Python. Remember that opencv images are numpy arrays in Python.
