摘要：A procedure is presented to detect changes in a
video sequence based on the Viola & Jones Method to obtain
images of faces of persons; videos are taken of the web. The
software allows to obtain images or frames separated from nose,
mouth, and eyes but the case of the eyes is taken as an example.
Change detection is done by using correlation and the Harris
detector. The correlation results allow us to recognize changes in
position in the person or movement of the camera if the
individual remains fixed and vice versa. It is possible to analyze a
part of the face thanks to the Harris detector; It is possible with
detected reference points to recognize very small changes in the
video sequence of a particular organ; such as the human eye,
even when the image is of poor quality as is the case of videos
downloaded from the Internet or taken with a low-resolution
camera.
