Mathematical Approach and Results of Viola Jones Face Detection Method

Abstract

The fundamental rule of this methodology is to scan a sub-window fit for recognizing faces across a given input image. The standard image processing approach is rescale the input image to various sizes and afterward run the fixed size detector through these images. As opposed to the standard methodology Viola-Jones rescale the detector rather than the input image and run the detector ordinarily through the image – each time with an various size. The drawback of the previous work was that the accuracy level of detecting the human face was not very high. This approach tries to find out an automatic human face detection system that can detect  the faces and eyes and calculates the accuracy.
