in this video you will learn to handle mouse events in OpenCV, and you will learn cv2.setMouseCallback() function. First we will learn to create a black image,which is called canvas, on that canvas we will paint like a brush using mouse. First we will draw a circle wherever we double click on canvas. Next we will draw a rectangle shape using mouse. to get the shapes using mouse we have to use mouse events like, cv2.EVENT_LBUTTONDBLCLK, cv2.EVENT_LBUTTONDOWN, cv2.EVENT_MOUSEMOVE, cv2.EVENT_LBUTTONUP.
We have to create a function i.e, draw_circle(event,x,y,flags,param) to draw the circle and rectangle.
