Automatic 3-D unorganized point data registration technique,which maps datas measured from multiple viewpoints into a common coordinate space, is key technique for reverse engineering.In order to improve matching speed, parallel detecting algorithm with local geometric feature based on CUDA architechure was proposed.Firstly,local points were extracted original sets,and then the correspondence between them are computed, at last this implemented in pattern CUDA.The comparison experiments show...
Isometric transformation with geodesic distance is widely used in similarity analysis or 3D retrieval of non-rigid objects. However, sensitive to topology noise and can be problematic cases where objects changed locally. In order solve the problem, a new method based on diffusion map was proposed. We compute embedded models utilized thin-plate spline (TPS) match obtain error original The tested some examples, results show that suitable objects, moreover, our robust deformed noise.
Affective patterns based on physiological signals reflect bodily changes linked to specific emotional states. Previous studies the cardiac electrical signal, a key peripheral were limited by measurement density of single-lead ECG focusing solely temporal pattern analysis but ignoring topographic that can body’s response. Our research advances affective innovatively using body surface potentials comprehensively monitor activity with increased density. To tackle challenge extracting spatial...
Reconstructing geometry models from scattered data is an important task in reverse engineering. An adaptive subdivision surface reconstruction method was proposed to construct complex rapidly. This includes several steps: triangulation on data; mesh segmentation and simplification; computing the depth according specified error. The last step control net by fitting functions adaptively. In order improve efficiency of algorithm, we implemented algorithm GPU parallel way tested program large...
In order to smooth point-based surface with noise, Bezier fitting method was applied compute principal curvature and normal vector at each point. We construct an undirected weighted graph from scattered points, a heat diffusion partial differential equation defined on this graph. Considering as power, the smoothing process is realized by diffusing along structure. adapt position of point direction according difference curvature. Computing can be boiled down spectral decomposition Laplacian...
