Proxy Clouds for RGB-D Stream Processing

Work done during my PhD at Telecom ParisTech in collaboration with Ayotle SAS.
Collaborators: Prof. Tamy Boubekeur, Dr. Jose Alonso Ybanez Zepeda

Keywords: RGB-D images, Scene analysis, Geometric analysis, 3D point cloud, 3D geometric primitives, planes, Data accumulation, High level superstructure, Live processing, Depth improvement, Data reinforcement, 3D data compression

Modern RGB-D sensors are widely used for indoor 3D capture, with applications ranging from modeling to robotics, through gaming. Nevertheless, their use is limited by their low resolution, with frames often corrupted with noise, missing data and temporal inconsistencies. In order to cope with all these issues, we propose Proxy Clouds, a multiplanar superstructure for unified real-time processing of RGB-D data. By generating and updating through time a single set of rich statistics parameterized over planar proxies and fed from raw RGB-D data, Proxy Clouds support several processing primitives which improve the quality of the RGB-D stream on-the-fly or lighten further operations. As a result, Proxy Clouds provides a light weight analysis framework which copes well with embedded execution as well as moderate memory and computational capabilities. Proxy Clouds can be used for several applications, including noise and temporal flickering removal, hole filling, resampling, color processing and compression.
