What is vision cascade object detector Matlab?

The cascade object detector uses the Viola-Jones algorithm to detect people's faces, noses, eyes, mouth, or upper body. You can also use the Image Labeler to train a custom classifier to use with this System object. For details on how the function works, see Get Started with Cascade Object Detector.

What is Cascade detector?

CascadeObjectDetector System object detects objects in images by sliding a window over the image. The detector then uses a cascade classifier to decide whether the window contains the object of interest. The size of the window varies to detect objects at different scales, but its aspect ratio remains fixed.

How does Haar cascade classifier work?

Haar cascade works as a classifier. It classifies positive data points → that are part of our detected object and negative data points → that don't contain our object. Haar cascades are fast and can work well in real-time. Haar cascade is not as accurate as modern object detection techniques are.
