N2 - This paper describes a method for accurately interpolating a low-resolution depth image using a high-resolution color image. In our method, first, tangent planes on each superpixel are estimated from sparse depth information and dense color information. Then, the neighboring superpixels that have smooth-connectable tangent planes are connected, and image segmentation to smooth surfaces is achieved. Finally, the low-resolution depth image is interpolated by using this smooth surface segmentation. In experiments with images from the Middlebury stereo data sets, our method interpolates each image at a high rate, and achieves the lowest error when compared to existing techniques.
