Shape from focus technique can be used in the computer monocular vision, which is widely applied in the smart transportation. In this study, we proposed a novel directional statistics based focus measure for shape from focus computation. We first compute the standard deviation σ and the mean value μ in the directional neighborhood. Then use the σ/μ as the focus measure to estimate the shape. The proposed...
This paper presents a system for robust dynamic human surface reconstruction using a single Kinect. The single Kinect provides a self-occluded and noisy RGBD data. Thus it is challenging to track the whole human surface robustly. To overcome both incompleteness and data noise, we adopt a template to confine the shape in the un-seen part, and propose a two-stage tracking pipeline. The first stage tracks...
In this paper, an analysis of the spatial and temporal landscape evolution of northwest Sichuan Province, China, is carried out based on the landscape theory, RS and GIS. Fucheng District in Mianyang City, Sichuan Province, is chosen as our study area, and the driving forces of its landscape evolution are discussed based on the land use maps, the Landsat TM/ETM+ and CBERS 2B remote sensing images...
A skeleton graph matching algorithm based on a novel shape tree is proposed in this paper. The shape tree in this paper represents an object shape by simultaneously taking account of both the positive curvature maxima and negative curvature minima of the boundary based on skeleton. Comparing with the existing shape representation scheme, it's less time-consuming. Based on the proposed shape tree,...
