In this paper we present a method for fast surface reconstruction from large noisy datasets. Given an unorganized 3D point cloud, our algorithm recreates the underlying surface’s geometrical properties using data resampling and a robust triangulatio
We present a method for identifying a partial match for twice differentiable curves. The method uses equal arc-length interval correspondences when comparing points on one curve to another. We use the square of difference in curvatures at each point
三维大变形产生内禀纽结I:曲率，肖建华，，For a medium suffered large deformation, knots may be produced internally. Such a kind of knotted medium will reduce the elasticity of the medium. In this research, intrinsic knot
三维大变形产生内秉纽结II:多尺度，肖建华，，Once micro-scale intrinsic curvatures are produced within the material by large deformation in 3-space, what physical feature can be used to identify their existence? Based on the
Forstner(1986)和Harris and Stephens(1988)是第一个提出使用自相关矩阵导出的旋转不变标量测量的局部最大值来定位关键点以达到匹配系数特征目的的AUTO-CORRELATION DETECTOR
The solution to this problem is to attempt to detect both
edges and corners in the image: junctions would then
The performance of Morave
The aim of this work is to provide an analytical method based on experimental measurements in order to obtain the prismatic film deformation for different curvatures of hollow cylindrical prismatic light guides (CPLGs). To conform to cylindrical guid
Measuring the variation of the output" power of a waveguide CO2 laser with coupling distance for different curvatures of the cavity mirror, a minimal coupling loss point is obtained. Experimental results show that the frequency tuning range can thus
