| Popis: | In this paper, we propose the method of estimating the coordination of the mouth position with the head movement. This is done by using image processing technology. The mouth position will be able to use the human interface to control the meal support robot. The estimation method for the coordinate of the mouth position is as follows. Firstly, we extract the area of the mouth from the time series images by two video cameras. Secondly, we describe the method to estimate the head movement from the coordinate of the mouth center. Finally, we calculate the 3D coordinate of the mouth center to apply to some parallel images. |
