Abstract

The vision sensor of a conventional mobile robot is attached to the body of the robot. For more flexible environment recognition, it is necessary to allow the vision sensor to controlling visual attention mechanism of a mobile robot, and examine a method for obtaining a local map. A set of equations which produces the local map from continuous observational data is described. Advantages of the controlling visual attention are presented, based on an error analysis. The advantages are that the environment can be obtained from a coordinate system based on the object under attention, and that errors in the determined position of the object are smaller than with other methods which do not include a controlling visual attention. Experimental results using a Kalman filter for a set of continuous observational data show that an accurate local map is produced.

We present a method to estimate a dense and sharp depth map using multiple cameras. A key issue for obtaining sharp depth map is how to overcome the harmful influence of occlusion. Thus, we first propose an occlusion-overcoming strategy which selectively uses the depth information from multiple came

Background. Non-union of mandibulotomies is a serious complication but risk factors are unclear. No data are available on the effect of the specific dose of irradiation at the osteotomy site. Methods: Forty-eight patients (36 men, 12 women, median age 58 years) undergoing a mandibulotomy and postop
