Vehicle anti-collision technique is a hot topic in the research area of Intelligent Transport System. The research on preceding vehicles detection and the distance measurement, which are the key techn
The wavelet transform has remarkable advantages and wide applications in denoising because of its characteristic of good time-frequency. Based on the analysis of traditional wavelet denoising methods,
A simulation method for visible and near infrared(VNIR) image is mentioned.The VNIR image obtained by low-level flight is adopted as data resource.After atmospheric correction,the ground reflectivity
We show that the extremal polygonal quasiconformal mappings are biLipschitz with respect to the hyperbolic metric in the unit disk.
A new multispectral image fusion method based on intensity-hue-saturation(IHS) transform and threechannel non-separable wavelets whose dilation matrix is[2,1;1,1]is proposed.The multi-resolution decom
A novel radiometric compensation algorithm is proposed to correct the color distortions of the projection display on patterned surface.Two choices of the objective image are investigated in this algor
物理学课程的特殊性,特别是深奥难懂的复杂公式和物理内涵使很多大学生对物理学望而生畏,而可视化软件的发展具有简单易学,公数据可视化等特点,有助于解决这一难题。因此,有必要针对物理系的学生开设特定的软件课程,比如Matalab,Maple或者Mathematica,这对于推进我国物理教学的发展,提高学生的兴趣,培养出高质量的复合型人才具有重要意义。
构造性实体几何法(简称CSG)在构造计算机几何图形上有着广泛的应用。然而,在构造凹面体立体图形时,传统的CSG算法并不能满足需要。本文利用BSP算法实现构造性实体几何,并给出部分实现代码。
This paper describes a method based on an energy minimizing deformable model applied to the 3D biomechanical modeling of a set of organs considered as regions of interest (ROI) for radiotherapy. The i
In this paper,a new multiclass classification algorithm is proposed based on the idea of Locally Linear Embedding(LLE),to avoid the defect of traditional manifold learning algorithms,which can not dea
