Are Textureless Scenes Recoverable?

چکیده
It is widely accepted that textureless surfaces cannot be recovered using passive sensing techniques. The problem is approached by viewing image formation as a fully threedimensional mapping. It is shown that the lens encodes structural information of the scene within a compact threedimensional space behind it. After analyzing the information content of this space and by using its properties we derive necessary and sufficient conditions for the recovery of textureless scenes. Based on these conditions, a simple procedure for recovering textureless scenes is described. We experimentally demonstrate the recovery of three textureless surfaces, namely, a line, a plane, and a paraboloid. Since textureless surfaces represent the worst case recovery scenario, all the results and the recovery procedure are naturally applicable to scenes with texture.

متن کاملNear Real-time Stereo for Weakly-Textured Scenes
Several real-time/near real-time stereo algorithms can currently provide accurate 3D reconstructions for well-textured scenes. However, most of these fail in sufficiently large regions that are weakly textured. Conversely, other scene reconstruction algorithms assume strong planarity in the environment. Such approaches can handle lack of texture, but tend to force nonplanar objects onto planes....
متن کاملImproving Depth Maps by Nonlinear Diffusion
Dense depth maps, typically produced by stereo algorithms, are essential for various computer vision applications. For general configurations in which the cameras are not necessarily parallel or close together, it often proves difficult to obtain reasonable results for complex scenes, in particular in occluded or textureless regions. To improve the depth map in such regions, we propose a post-p...
متن کاملA Fault-Tolerant Algorithm of Wireless Sensor Network Based on Recoverable Nodes
In wireless sensor networks, the node faults often occurred in scenes because of severe disturbance, harsh environment and inherent weakness of the networks. In this paper, a fault tolerance directed diffusion protocol, termed fault-tolerant algorithm with recoverable nodes (FTA-RN), is proposed to extend the lifetime of the wireless sensor network based on recoverable host nodes, in which a he...
متن کاملFocus Range Sensors
Structures of dynamic scenes can only be recovered using a real-time range sensor. Focus analysis offers a direct solution to fast and dense range estimation. It is computational efficient as it circumvents the correspondence problem faced by stereo and feature tracking in structure from motion. However, accurate depth estimation requires theoretical and practical solutions to a variety of prob...
