Object Detection using Haar feature-based cascade classifiers is an effective object detection method proposed by Paul Viola and Michael Jones in their paper, "Rapid Object Detection using a Boosted Cascade of Simple Features" in 2001. It is a machine learning based approach where a cascade function is trained from a lot of positive and ...

In simple terms, each feature acts as a binary classifier in a cascade filter. If an extracted feature from the image is passed through the classifier and it predicts that the image consists of that feature then it is passed on to the next classifier for next feature existence check otherwise it is discarded and next image is checked.

the Haar Cascade method with CNN is done because CNN takes a long time to detect objects in real-time. Also, the Haar Cascade method is used to retrieve bounding boxes from vehicles before they can be detected by CNN. The advantage of the Haar Cascade Classifier method is a very fast computation process because this

In the deep cascade stage, each layer uses several centroid classifiers as base classifiers. The first-layer centroid classifiers receive features extracted by the feature scanning stage as input, after centroid classifier calculations, and the results are used as input for the second-layer centroid classifiers.
