Color segmentation based depth image filtering

Abstract

We present a novel enhancement method that addresses the problem of corrupted edge information in depth maps. Corrupted depth information manifests itself in zigzag edges instead of straight ones. We extract the depth information from an associated color stream and use this information to enhance the original depth map. Besides the visual results, a quantitative analysis is conducted to prove the capabilities of our approach. For this task, we introduce a new assessment technique which is based on measuring clustering similarity using the Rand index. © 2013 Springer-Verlag.
