摘要: This paper describes some simple but useful computer vision techniques for human-robot interaction. First, an omnidirectional camera setting is described that can detect people in the surroundings of robot, giving their angular positions and a rough estimate distance. The device be easily built with inexpensive components. Second, we comment on color-based face detection technique alleviate skin-color false positives. Third, head nod shake detector described, suitable detecting affirmative/negative, approval/dissaproval, understanding/disbelief gestures.
