Description: 本程序实现hough变换。Hough变换是图像处理中从图像中识别几何形状的基本方法之一。Hough变换的基本原理在于利用点与线的对偶性,将原始图像空间的给定的曲线通过曲线表达形式变为参数空间的一个点。这样就把原始图像中给定曲线的检测问题转化为寻找参数空间中的峰值问题。也即把检测整体特性转化为检测局部特性。比如直线、椭圆、圆、弧线等。

Description: Hough变换利用图像空间和Hough参数空间的点-线对偶性,把图像空间中的检测问题转换到参数空间。通过在参数空间里进行简单的累加统计,然后在Hough参数空间寻找累加器峰值的方法检测直线。例如,图1(a)中的九条线段对应于如图1(b)所示的其Hough参数空间的九个累加器峰值。图1(b)中,Hough参数空间的横纵坐标分别为直线极坐标方程:ρ=x×cos(θ) + y×sin(θ) 的两个参数ρ和θ。九个峰值的ρ和θ值唯一的确定其对应线段所在直线的两个参数。并且线段的长度决定坐标(ρ,θ)处的累加值的大小。,Hough transform using the image space and Hough parameter space point- line duality, the detection problem in the image space conversion to the parameter space.

Description: FM调制和解调,matlab语言实现,可以改变fs,fc,ft - Fisher4Cast
Authors: Bruce A. Bassett, Yabebal Fantaye, Renee Hlozek and Jacques Kotze
The Fisher4Cast suite provides a standard, tested tool set for general Fisher Information matrix prediction and forecasting for use in both research and education. The toolbox design is robust and modular, allowing for easy additions and adaptation while keeping the user interface intuitive and easy to use. Fisher4Cast is completely general but the default code is written for cosmology. It provides parameter error forecasts for cosmological surveys that provide distance, Hubble expansion and growth measurements in a general, curved FLRW background. See the accompanying paper, http://arxiv.org/abs/0906.0993 , for further details and examples of novel applications in Observational Cosmology.
The release package contains documentation (Manual, Quickstart guide and sample code to produce figures) in addition to the code which can be run in both command line and GUI format (th Platform: |

Description: 本程序研究的目的是证明一种有限元相场算法,其中相场方程是完全耦合并同时求解的。不过,在这种情况下,完全耦合的方程是弹性和非守恒的阶参数;然而,该方法可作为其他相场模型完全耦合公式的模板。这是求解具有弹性不均匀性的Allen-Cohn方程的主要程序。有限元算法。该算法解决了非保守阶参数的演化问题。全耦合模式下应力列场的演化。取决于代码中Isolve参数的选择:对于Isolve-1,代码以长手格式和非优化模式执行。为了执行Matlab优化模式。因此,对于所需的执行模式,该参数应该在程序中修改。(The objective of this program is to demonstrate a FEM phase-field algorithm in which
phase-field equations are fully coupled and solved simultaneously. Although, in this case, the fully coupled equations are elasticity and non-conserved order parameters; however, the approach serves as a template for fully coupled formulism of other phase-field models. This is the main program to solve Allen-Cohn equation with elastic inhomogeneities using FEM algorithm. The algorithm solves the evolution of the non-conserved order parameters and the evolution of stress and strain fields simultaneously in fully coupled mode. Depending on the selection of the isolve parameter in the code: For isolve=1, the code executes in longhand format and un-optimized mode. For isolve=2, execution is for Matlab Octave optimized mode. Therefore, for the desired execution mode, this parameter in line 37 should be modified in the program.) Platform: |
