Problems solved by technology

Such facial area tracking technology using dynamic templates is suitable for real-time tracking of fast-moving facial areas because the images used as templates are updated in real time. However, as long as the tracking results make an error, it is impossible to recover. The face area is tracked as a template, so there is a problem that errors are accumulated for each successively input image and the accuracy decreases
In addition, there is a problem that the automatic initialization is limited because the user manually sets the initial template when tracking the face area.

Abstract

The present disclosure is directed to performing head tracking. The method comprises: (a) receiving an input of an image including a facial area; and (b) tracking a movement of the facial area. The step (b) comprises: (b-1) if a rotation angle of a facial area is within a predetermined angle range from a front side, searching for a location change of feature points within a facial area through a comparison with a template learned in advance; and (b-2) if a rotation angle of a facial area is beyond a predetermined angle range from a front side, searching for a location change of feature points within a facial area through a comparison with a facial area image frame previously inputted.

Description

technical field [0001] The present invention relates to a head tracking method, device, and computer-readable recording medium, and more particularly relates to performing tracking by inferring the above-mentioned face area as 3D after detecting the face area from a 2D image, if the angle of the face area is at a predetermined angle in the front The active appearance model (Active Appearance Model: AAM) algorithm is used under the situation within the specified angle, and the dynamic template (dynamic template) technology is used to infer the head tracking method, device and computer based on the feature of the head position when the angle is out of the specified angle. Read the recording medium. Background technique [0002] The technique of detecting faces is one of the researched areas in many application systems such as mobile robots, surveillance systems, human-robot interaction, command input using head tracking, etc. Although it is difficult to detect faces in real t...
