Abstract

This paper presents a method for improving the accuracy of template-based planar tracking. It has been shown that when the ROI of the input image has a lower resolution than the template, tracking accuracy will deteriorate; then, this can be remedied by blurring the template in response to the motion of the plane. In this study, we show that, conversely, when the template has a lower resolution than the input image, tracking accuracy will deteriorate in a different manner. We then present a method that can simultaneously deal with both cases and thus achieves higher tracking accuracy.
