Opencv image background subtraction
Background subtraction (BS) is a common and widely used technique for generating a foreground mask (namely, a binary image containing the pixels belonging to moving objects in the scene) by using static cameras. As the name suggests, BS calculates the foreground mask performing a … Ver mais In this tutorial you will learn how to: 1. Read data from videos or image sequences by using cv::VideoCapture; 2.
