High resolution depth image recovery algorithm based on the modeling of the sum of an average distance image and a surface image

This paper proposes a new depth image recovery algorithm which recovers a high resolution depth image using RGB color image from a very low resolution depth image. In order to achieve a high recovery performance, this paper represents the high resolution depth image as the sum of an average distance image and a surface image. Experimental examples show that the proposed algorithm achieves a high resolution depth recovery from a very low resolution depth image effectively.
