The first parameter that we must feed into the cv2.line() function is the image we want to draw it on. We will be using what we created with numpy, whiteblankimage. This provides a perfect clean white background, in which we can place our line shape. The second parameter we must spe...
When we need to draw a rectangle on an image or plain figure in Matplotlib, the rectangle patch from matplotlib.patches should be added to the axes by add_patch method. ADVERTISEMENT A Matpotlib patch is a 2-D artist that has a face and edge color. Matplotlib has patches like, Arc Arr...
