WebFollowing are the machine learning based object detection techniques: 1. Viola Jones face detector (2001) It was the first efficient face detection algorithm to provide competitive results. They hardcoded the features of the face (Haar Cascades) and then trained an SVM classifier on the featureset. Then they used that classifier to detect faces. WebSIFT Detector. Scale-Invariant Feature Transform (SIFT) is another technique for detecting local features. The Harris Detector, shown above, is rotation-invariant, which means that the detector can still distinguish the corners even if the image is rotated. However, the Harris Detector cannot perform well if the image is scaled differently.
