WebIf you are interested to detect simple IR light blob through haar cascade, it will be very odd to do. Because simple IR blob does not have enough features to be trained through opencv like other objects (face, eyes,nose etc). Because IR is just a simple light having only one feature of brightness in my point of view. WebHaar Cascade algorithm is one of the most powerful algorithms for the detection of objects specifically face detection in OpenCV proposed by Michael Jones and Paul Viola in their research paper called “Rapid …
