Viewpoint Estimation based on Moment Feature

Abstract

This paper proposes viewpoint estimation method intended to be used as the basic device to estimate user's intension in a visual environment. Our method is based on moment feature which represents non-local feature of image, such as the gravity center or the breadth, and has less computational cost and considerable robustness to noise. We also propose the form and use of marker suitable for our purpose. That is, putting an oval marker on the top of a user's head. Experimental result shows that our method has good performance.
