If you had to detect vehicles using ONLY motion detection, how would you do it? 🔍

​ I’m working on a computer-vision problem where I need to detect vehicles (cars, trucks, buses, etc.) using only traditional image-processing/computer-vision techniques. The important constraint is: * ❌ No YOLO / deep-learning detector * ❌ No object detection model * ❌ No neural networks * ✅ Motion detection and traditional CV techniques only The camera is fixed, so the general idea is to identify regions that correspond to moving vehicles. I’m considering approaches such as: * Background subtraction (MOG2 / KNN) * Frame differencing * Optical flow * Contour detection * Morphological operatio
