A Dynamic 3D Human Model using Hybrid 2D-3D Representations in Hierarchical PCA Space
نویسندگان
چکیده
We propose a novel framework for a hybrid 2D-3D dynamic human model with which robust matching and tracking of a 3D skeleton model of a human body among multiple views can be performed. We describe a method that measures the image ambiguity at each view. The 3D skeleton model and the correspondence between the model and its 2D images are learnt using hierarchical principal component analysis. Tracking in individual views is performed based on CONDENSATION.

متن کاملTarget detection Bridge Modelling using Point Cloud Segmentation Obtained from Photogrameric UAV
In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...
متن کامل2D-3D Hybrid Face Recognition Based on PCA and Feature Modelling
Hybrid face recognition, using image (2D) and structural (3D) information, has explored the fusion of Nearest Neighbour classifiers. This paper examines the effectiveness of feature modelling for each individual modality, 2D and 3D. Furthermore, it is demonstrated that the fusion of feature modelling techniques for the 2D and 3D modalities yields performance improvements over the individual cla...
متن کامل3D and 4D Seismic Data Integration in Static and Dynamic Reservoir Modeling: A Review
Reservoir modeling is the process of generating numerical representations of reservoir conditions and properties on the basis of geological, geophysical, and engineering data measured on the Earth’s surface or in depth at a limited number of borehole locations. Therefore, reservoir modeling requires an incorporation of the data from a variety of sources, along with an integration of knowledge a...
متن کاملAn accurate 3D human face model reconstruction scheme
The purpose of this thesis was to develop a 3-dimensional (3D) reconstruction algorithm which can more accurately generate a 3D shape model of a human face from a single 2-dimensional (2D) image. Like most present day approaches to building 3D human facial models, the proposed algorithm stemmed from the statistical approach pioneered by Blanz and Vetter [13], who used a morphable 3D model which...
