Proxy Clouds for Live RGB-D Stream Processing and Consolidation

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, Scene reconstruction, 3D data compression

We propose a new multiplanar superstructure for unified real-time processing of RGB-D data. Modern RGB-D sensors are widely used for indoor 3D capture, with applications ranging from modeling to robotics, through augmented reality. Nevertheless, their use is limited by their low resolution, with frames often corrupted with noise, missing data and temporal inconsistencies. Our approach, named Proxy Clouds, consists in generating and updating through time a single set of compact local statistics parameterized over detected planar proxies, which are fed from raw RGB-D data. Proxy Clouds provide several processing primitives, which improve the quality of the RGB-D stream on-the-fly or lighten further operations. Experimental results confirm that our light weight analysis framework copes well with embedded execution as well as moderate memory and computational capabilities compared to state-of-the-art methods. We propose several applications based on Proxy Clouds, including noise and temporal flickering removal, hole filling, resampling, compression and scene reconstruction. We present experiments performed with our framework in indoor scenes of different natures within a recent open RGB-D dataset.

A Survey of Simple Geometric Primitives Detection Methods for Captured 3D Data

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

Keywords: 3D data, 3D geometric primitives, Shape analysis, Shape abstraction, Geometric modeling, Data fitting

The amount of captured 3D data is continuously increasing, with the democratization of consumer depth cameras, the development of modern multi-view stereo capture setups and the rise of single-view 3D capture based on machine learning. The analysis and representation of this ever growing volume of 3D data, often corrupted with acquisition noise and reconstruction artifacts, is a serious challenge at the frontier between computer graphics and computer vision. To that end, segmentation and optimization are crucial analysis components of the shape abstraction process, which can themselves be greatly simplified when performed on lightened geometric formats. In this survey, we review the algorithms which extract simple geometric primitives from raw dense 3D data. After giving an introduction to these techniques, from the acquisition modality to the underlying theoretical concepts, we propose an application-oriented characterization, designed to help select an appropriate method based on one's application needs, and compare recent approaches. We conclude by giving hints for how to evaluate these methods and a set of research challenges to be explored.
