The first method for counting people in a video stream is to distinguish each individual object with the help of machine learning algorithms. For this purpose, the HOGDescriptor class has been implemented in OpenCV. HOG (Histogram of Oriented Gradients) is a feature descriptor used in computer vision and image processing to detect objects.
OpenCV was designed for computational efficient applications and has a strong focus on real-time applications. Moreover, if OpenCL is employed, it can take advantage of the hardware acceleration. We will learn how to apply a face detection algorithm with OpenCV to single input images.
Jun 26, 2016 · And there you have it! You just did color matching in OpenCV. We found an upper and lower bound for the shade of red that we were looking for, and created a mask that only had white pixels filled in for wherever there was a red that matched. The next tutorial in this OpenCV series is Canny Edge Detection in Python with OpenCV.
James Bond is a car thief. The movies show that he has stolen many automobiles, often from innocent bystanders. We do not know whether these unfortunate people ever recovered their property but, even if they did, the damages from collisions, submersions, bullets, and rockets would have had a lasting impact on their insurance premiums.
