METHOD TO DETERMINE AND VISUALIZE LINE-OF-SIGHT

A METHOD TO DETERMINE AND VISUALIZE HUMAN LINE-OF-SIGHT FROM A SEQUENCE OF IMAGE IS DESCRIBED. FIRST, A MOTION BLOB IS DETECTED FROM THE IMAGE (20). THEN, THE HUMAN LOCATION FROM THE MOTION BLOB IS DETECTED AND TRACKED (30) BY ENCLOSING A RECTANGLE AROUND THE BOUNDARIES OF THE BLOB. THE FACE REGION...

Zusammenfassung:A METHOD TO DETERMINE AND VISUALIZE HUMAN LINE-OF-SIGHT FROM A SEQUENCE OF IMAGE IS DESCRIBED. FIRST, A MOTION BLOB IS DETECTED FROM THE IMAGE (20). THEN, THE HUMAN LOCATION FROM THE MOTION BLOB IS DETECTED AND TRACKED (30) BY ENCLOSING A RECTANGLE AROUND THE BOUNDARIES OF THE BLOB. THE FACE REGION IS THEN DETECTED FROM THE BLOB (40). AFTER THAT, THE GAZE DIRECTION FROM THE BLOB IS DETECTED (50). LATER, THE LINE-OF-SIGHT IS VISUALIZED FROM THE FACE REGION TOWARDS A DIRECTION DETERMINED BY GAZE DIRECTION (70). THE HUMAN BLOB AND VISUALIZATION IS REPRESENTED IN A 3-DIMENSIONAL CUBE CORRESPONDING TO THE SEQUENCE OF IMAGE.
