本文提出了一种深度图像恢复算法，利用灰度图像和低分辨率深度图像恢复深度图像。基于图像彩色化技术，将深度值图像恢复问题转化为凸二次优化问题，提出了一种快速深度图像恢复算法。实验结果表明，该算法能有效地从低分辨率深度图像恢复高分辨率深度图像。
This paper proposes a depth image recovery algorithm which recovers depth images using grayscale images and low resolution depth images. Based on a image colorization technique, a depth value image recovery problem is formulated as a convex quadratic optimization problem, and a fast depth image recovery algorithm is proposed. Experimental results show that the proposed algorithm recovers a high resolution depth image from a very low resolution depth image effectively.
