一篇介绍粒子滤波的资料，介绍的很详细，适合研究粒子滤波的初学者，希望对大家有帮助(Introduce a particle filter information on the very detailed study of particle filter is suitable for beginners)

说明：  matlab函数进行图像轮廓处理，处理效果还是可以的。(matlab function detect the picture and scale the picture)

进行分数傅立叶变换的算法，通过该算法可以对函数进行任意分数阶傅立叶变换(For the fractional Fourier transform algorithms, the adoption of the algorithm can function for arbitrary fractional order Fourier transform)

gabor特征提取程序，对于搞问纹理提取的人来说很有用处(gabor feature extraction process, engage in asking for the texture extraction is very useful for those who)

说明：  已知质量阻尼弹簧系统的运动微分方程，求系统何时达到稳定，并画出位移时间变化曲线(Known mass damper spring system equations of motion, seeking when the system reaches stability, and draw the displacement-time curve)

对图像进行模糊处理前的第一步设计操作，然后进行加强滤波处理(Fuzzy image processing operation prior to the first step in the design and then proceed to strengthen the filter processing)

该代码用于实现视觉目标跟踪研究中的协方差跟踪，能够把多种时空特征融合于统一的模型中，在实现视觉目标跟踪时具有较好的鲁棒性，而且其维数等于使用特征的数量，与各个特征的维数无关，因此，其计算复杂度较小，实时性较好。(This code is used to realize covariance tracking in the research field of visual object tracking of computer vision. It enables fusion of various spatial-temporal features into an unified object feature model, hence robust to noise. In addition, its dimension is equal to the number of the features used and independent of the dimensions of the features used. Therefore, it satisfies the requirement of real-time application due to its low computation cost.)

本程序实现了提取图像中直线的功能。能够很好地提取出位于边缘上的直线段，其结果表示为两端端点坐标以及线段宽度(This program realizes the function of extracting the edge line in the image.The straight line segment at the edge can be extracted well, and the result is expressed as the end point coordinates and line segment width at both ends.)

说明：  实现图像受混合噪声污染时去除噪声的目的，在6种方法比较之下，得出最优的图像去噪算法(Image by mixed noise pollution when the purpose of removing noise, in the six kinds of methods of comparison, the optimum image denoising algorithm)
