摘要

结构光RGB-D相机通常用于捕获深度图像,它传达场景中的每像素深度信息。然而,这些相机经常产生缺少像素的区域。缺失的像素区域(指孔)将不包含深度图像的任何深度信息。在现代三维(3D)视频应用中,这个原因会导致性能严重下降。因此,如何有效地利用图像信息和深度图变得越来越重要。本文提出了基于纹理相似度的自适应钻孔填充(ATSHF)和基于纹理相似度的自适应深度增强(ATSDE)。该系统通过抑制噪声、填充孔洞和锐化物体边缘来实现深度图的增强。实验结果表明,该方法具有较好的性能,特别是在目标边界附近。此外,我们还比较了目前最先进的图像增强方法和深度图增强方法。

Efficient hole filling and depth enhancement based on texture image and depth map consistency
Structured-light RGB-D cameras are commonly used to capture depth images, which convey the per-pixel depth information in a scene. However, these cameras often produce regions with missing pixels. The missing pixel regions, which refer to holes, will not contain any depth information for the depth image. This reason would lead the performance to degrade seriously in modern-day three-dimensional (3D) video applications. Therefore, how to effectively utilize image information and depth maps become more and more important. In this paper, we propose adaptive texture-similarity-based hole filling (ATSHF) and adaptive texture-similarity-based depth enhancement (ATSDE). The proposed system, which is used for the enhancement of depth maps, is achieved by suppressing the noise, filling holes and sharpening object edges simultaneously. Experimental results demonstrate that the proposed method provides a superior performance, especially around the object boundary. Beside, we compare with the other state-of-the-art methods about the image and the depth map enhancement.
