Depth refinement shading ppt
WebDownload BibTex. We present a shading-based shape refinement algorithm which uses a noisy, incomplete depth map from Kinect to help resolve ambiguities in shape-from-shading. In our framework, the partial depth information is used to overcome bas-relief ambiguity in normals estimation, as well as to assist in recovering relative albedos, which ... WebDec 3, 2024 · Depth estimation is an essential component in understanding the 3D geometry of a scene, with numerous applications in urban and indoor settings. These scenes are characterized by a prevalence of human made structures, which in most of the cases, are either inherently piece-wise planar, or can be approximated as such. In these …

WebSep 19, 2016 · In this paper, we show that the IR camera of the Kinect is not only useful in the depth measurement, but also useful for capturing shading cues of a scene that allow higher quality reconstruction than the Kinect fusion (Izadi et al. 2011 ), which only uses the estimated depth map for 3D reconstruction. WebWhile modern shading based depth refinement methods have been proven to work well with Lambertian objects, they break down in the presence of specularities. We present a novel shape from shading framework that addresses this issue and enhances both diffuse and specular objects' depth profiles. We take advantage of the built-in monochromatic IR ...
WebCVF Open Access WebThis paper presents a spatial-varying illumination model for shading-based depth refinement that based on a smooth Spherical Harmonics (SH) lighting field. The proposed lighting model is able to recover shading under challenging unknown lighting conditions, thus improving the quality of recovered surface detail.

In this paper, we propose a simple … WebDepth IMAGE PLANE 13 NORMAL MAP vs. DEPTH MAP Can determine Depth Map from Normal Map by integrating over gradients p,q across the image. Not all Normal Maps have a unique Depth Map. This happens when Depth Map produces different results depending upon image plane direction used to sum over gradients.
