Description: 里查得森(Richardson)法解偏微分方程的程序。解的是定步长的抛物型偏微分方程:
du/dx - a * d2u/dx2 = 0
在程序中可以更改 a 的值以实现不同系数的解。由于它是一种显式格式,解的结果不稳定
在Matlab7下面运行发现竟然有一些值达到十的几十次方,这是算法本身决定的。不是程序有错误-Richard Anderson (Richardson) Solving partial differential equations procedures. Solution is scheduled to step parabolic partial differential equation: du/dx- a* d2u/dx2 = 0 in the procedure can be changed in order to realize the value of a different coefficient of the solution. Because it is an explicit format, the result of instability in the solution of the following Matlab7 running even found some value reached ten dozens of parties, this is the decision algorithm itself.

Description: A generalized Richardson extrapolation routine that can perform multiple extrapolation steps, can accommodate arbitrary leading error terms, can handle any uniform refinement scheme (e.g. h/2, h/3, h/5, etc), and can report a full extrapolation table including comparing against a known good solution. Able to handle vector inputs. Compatible both with MATLAB and Octave. Includes Octave-style unit tests. Platform: |

Description: The Blind Deconvolution Algorithm can be used effectively when no information about the distortion (blurring and noise) is known. The algorithm restores the image and the point-spread function (PSF) simultaneously. The accelerated, damped Richardson-Lucy algorithm is used in each iteration. Additional optical system (e.g. camera) characteristics can be used as input parameters that could help to improve the quality of the image restoration. PSF constraints can be passed in through a user-specified function Platform: |

Description: The Lucy-Richardson algorithm can be used effectively when the point-spread function PSF (blurring operator) is known, but little or no information is available for the noise. The blurred and noisy image is restored by the iterative, accelerated, damped Lucy-Richardson algorithm. The additional optical system (e.g. camera) characteristics can be used as input parameters to improve the quality of the image restoration. Platform: |

Description: 盲去卷积复原算法,并在MATLAB中进行实验,和维纳滤波的复原效果进行一个对比。盲去卷积的方法有多种,露西-理查德森算法属于图像复原中的非线性算法,与维纳滤波这种较为直接的算法不同,该算法使用非线性迭代技术,在计算量、性能方面都有了一定提升(The blind deconvolution restoration algorithm is carried out in MATLAB and is compared with the restoration effect of Wiener filtering. There are many ways of blind deconvolution. Lucy Richardson algorithm is a nonlinear algorithm in image restoration. Unlike Wiener filtering, this algorithm uses nonlinear iteration technology, and has a certain improvement in computation and performance.) Platform: |

Description: 由于无人机在航拍时会受到相对运动、姿态变化、光学环境、机械振动等因素的影响,导致所拍图像退化。本文使用MATLAB对无人机航拍图像退化过程进行了仿真实验,根据图像退化的原因建立相应的图像退化模型,把清晰的原图像进行退化处理,然后将模拟出来的退化图像分别使用维纳滤波、约束最小二乘(正则)滤波、Lucy-Richardson迭代非线性和盲解卷积4种不同的复原算法进行恢复,达到复原模糊图像的目的。(The application of UAV aerial photography became more and more widely. As the UAV in the aerial photography would be subject to relative movement, posture changes, optical environment, mechanical vibration and other factors which had resulted in the image degradation. In this paper, I used MATLAB to simulate the degradation process of UAV aerial image. According to the reason of image degradation, I established the corresponding image degradation model and the original image was degraded. Then simulated degraded images respectively used the wiener filter, constrained least squares (regular) filtering, Lucy - Richardson iterative nonlinear and blind convolution four different restoration algorithms for recovery, achieved the goal of restoring blurred image.)
