有关粒子滤波及其改进算法的资料，对初学粒子滤波算法的人很有帮助(Information about particle filter and its improved algorithm, is of great help to beginners of particle filter algorithm )

锐化效果显示图像 例子

求一个图像的最大内接矩形面积。 步骤： 1.相机标定。首先根据物像关系式求出其中的参数。注意参数求出后要进行参数校验。 2.从背景中分离出目标 3.边缘检测 4.目标形状参数计算。(For an image of the largest inscribed rectangle area. Steps: 1. Camera calibration. First of all object-image relationship in accordance with the parameters obtained. Attention to the parameters obtained after parameter calibration. 2. From the context of isolated target 3. Edge detection 4. Target shape parameters.)

数值实现施瓦兹-克里斯多夫变换 可将一般区域保角映射为单位圆，条形带，方形等等基本区域，包含manual. matlab源码，有GUI，可实现点、点映射的显示(Numercial realization of the Schwarz-Christoffel Conformal Mapping)

matlab 马尔科夫随机场简单的实现例子(Markov random field matlab implementation simple example)

數據繪圖時候有時候必須處理資料矩陣轉向，該編碼詳細說明如何處理矩陣在三維度空間下進行轉向，而不是利用Curve Fitting Tools(Data drawing sometimes has to deal with the data matrix steering, which details how to handle the matrix to steer in a three-dimensional space instead of using Curve Fitting Tools)

说明：  基于matlab车牌识别系统，主要涉及图像预处理、车牌定位、倾斜角矫正、字符切割、字符识别五个模块(License plate recognition system based on MATLAB.It mainly involves five modules: image preprocessing, license plate location, tilt angle correction, character cutting and character recognition)

散点图数据输入，绘制，输出整个过程， 对于文章出图很有帮助。(Scatter plot data entry, rendering, output the entire process, the article showing helpful.)

利用数字图像处理(matlab第二版)中已学过的知识，进行各种图像加噪，去噪处理，复原，增强，以及彩色图像分割处理，(The use of digital image processing (matlab second edition) has been learned in the knowledge, a variety of image noise, denoising, restoration, enhancement, and color image segmentation,)

说明：  本程序提出了变步长自适应滤波算法的步长调整原则:即在初始收敛阶段或未知系统参数发生变化时,步长应比较大,以便有较快的收 敛速度和对时变系统的跟踪速度 而在算法收敛后,不管主输入端干扰信号v ( n) 有多大,都应保持很小的调整步长以达到很小的稳态失调噪声. 根据变步长公式编的程序，很有参考价值. (This procedure, a variable step adaptive filter algorithm step adjustment principle: that in the initial convergence phase or unknown system parameters change, the steps should be relatively large in order to have fast convergence speed and time-varying systems tracking speed in convergence, no matter the main input interference signal v (n) how much should be adjusted to maintain a small step to achieve a small steady state misadjustment noise. compiled according to the formula variable step procedure useful reference.)
