The Viola–Jones object detection framework is a machine learning object detection framework proposed in 2001 by Paul Viola and Michael Jones. It was motivated primarily by the problem of face detection, although it can be adapted to the detection of other object classes. The algorithm is efficient for its time, able to detect faces in 384 by 288 pixel images at 15 frames per second on a conventional 700 MHz Intel Pentium III. It is also robust, achieving high precisio… WebThe VJ face detector fea- tures in three aspects: fast feature computation via integral image representation, classifier learning using Adaboost, and the attentional cascade structure. One main drawback of the VJ framework is that the features have limited repre- sentation capacity, while the feature pool size is quite large to compensate for that.
