In this project i worked on a cascade classifier that helps in detecting car in which is present in a video stream , this algorithm helps in detcting the and tracking the amount and number of car present in a video and also it car be used in detecting the amount of vehicles and cars present in an image . A trained classifier that tracks object which is a car/vehicle.As haar cascade is used for object we have a very vast scope for this project .It also can be used for any type of object detection.We can also create our own custom haar cascade for specific objects.
