Visual Perception
You can detect objects using machine learning and deep learning techniques. You can also segment, detect, and model parabolic or cubic lane boundaries by using the random sample consensus (RANSAC) algorithm. After your detect objects, use Automated Driving Toolbox™ functions to evaluate and visualize the detections.
