Detecting direction of an object opencv

WebApr 9, 2024 · OpenCV provides several pre-trained models for object detection, including the Haar Cascade Classifier and the HOG+SVM detector. These models can be used to detect a wide range of objects, including faces, cars, and pedestrians. To use OpenCV for object detection, you first need to load the pre-trained model and the image or video … WebTracking is faster than Detection. Usually tracking algorithms are faster than detection algorithms. The reason is simple. When you are tracking an object that was detected in the previous frame, you know a lot about the appearance of the object. You also know the location in the previous frame and the direction and speed of its motion.

Object Tracking and Direction Detection using OpenCV

WebTracking is faster than detection. While the pre-trained classifier needs to detect an object at every frame of the video (which leads to potentially high computational loads), to utilize an object tracker we specify the bounding box of an object once and based on the data on its position, speed, and direction, the tracking process goes faster.
