Mat in python opencv.
If i blend them i get a transparent effect.
If i add two images it will change the color.
In this tutorial we shall learn how to resize image in python using opencv library.
So you can do it with bitwise operations as shown.
There are functions in opencv especially from calib3d module such as cv projectpoints that take an array of 2d or 3d points in the form of mat.
Src is the source original or input image in the form of numpy array.
