WebMar 9, 2013 · The codes available in this repo are tuned such that any score greater than 1.0 means they are a possible match. It works well with rotation and for images captured from different angles as well. However, if it is a 3D object (something with holes/gaps in between) and the view changes completely, it might not be possible for the algorithm to ... 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.
