Richter and Vladlen Koltun} title = {Depth Pro: Sharp Monocular Metric Depth in Less In this paper, we view face denoising from the perspective of implicit neural representation and propose a novel Depth Map Denoising Network (DMDNet) based on the Denoising Implicit Image Function (DIIF) to remove noises and improve the quality of facial depth images for low-quality 3D face recognition. How to get complete surface information, multi-scale depth map fusion Build a quality depth map in Fusion. These depth maps have their own characteristics. Our fusion approach learns sensor noise and outlier statistics and accounts them via confidence weights in the fusion process. While previous fusion methods use an explicit scene representation like signed distance functions (SDFs), we propose a learned feature representation for the fusion. Depth maps with a wide level of details are recovered by our method, which are helpful for many following and highly-related tasks such as image segmentation or 3D scene reconstruction. [15] estimate the prob Depth map super-resolution (SR) is an effective technology for recovering a high-quality depth map according to a low-resolution (LR) input. However, most depth estimation networks are based on a very deep network to extract features that lead to a large amount of information lost. Similar to the seminal depth map fusion approach by Curless and Levoy, A depth map fusion algorithm fuses depth maps from different perspectives into a unified coordinate framework and performs surface calculations to generate dense point clouds of the We introduce a learning-based depth map fusion framework that accepts a set of depth and confidence maps generated by a Multi-View Stereo (MVS) algorithm as inp The existing depth map fusion algorithms can be roughly divided into voxel-based fusion, feature-point-diffusion-based fusion and depth-map-based fusion. Each depth estimate votes for a voxel probabilisti-cally and the surfaces are extracted by thresholding. To enable a robot to navigate solely using visual cues it receives from a stereo camera, the depth information needs to be extracted from the image pairs and combined into a common To reconstruct a 3D scene from a set of calibrated views, traditional multi-view stereo techniques rely on two distinct stages: local depth maps computation and global depth maps fusion.
