Image Feature Extraction of Code

说明：  图像多尺度几何分析 contourlet 变换的matlab工具箱(Multiscale geometric analysis contourlet transform matlab toolbox)

This DataEntryFilter filters data entries based on whether their names match a given StringMatcher.

视觉注意力模型，寻找感兴趣区域，模仿人眼找出最感兴趣的区域，再找出第二感兴趣的区域，以此类推(Visual attention model to find the region of interest, to imitate the human eye to identify the most interesting region, and then find the second region of interest, and so on)

此程序是我进行视频处理时入门的程序，包含视频检测和轮廓跟踪，希望对大家有用(This program is my entry for video processing procedures, including video detection and contour tracing, hope for all of us)

说明：  matlab下面立体匹配和光流场计算代码，希望能对大家有所帮助。(matlab the following three-dimensional matching and optical flow field calculation code, hoping to be helpful to everyone.)

本程序对同一图像增加噪声后，进行均值滤波、高斯平滑滤波和中值滤波三种方法的去噪和结果比较， 并进行了评价指标PSNR和SSIM的计算以及算法耗时的统计。 ( The program on the same image after the noise increases, mean filter, de-noising and results of the Gaussian smoothing filter and median filter three methods of comparison, and the index PSNR and SSIM calculation algorithm and time-consuming statistics.)

图像配准。一个遥感图像配准函数。 双线性插值~ (image registration algorithm)

粒子滤波算法比较,不同的建议分布下，粒子滤波的性能差异，包括精度与时间(the comparision)

一个功能比较全面的图像处理系统，对初学者很有参考价值。(One features a more comprehensive image processing system, useful for beginners reference value.)

最小二乘法拟合圆vc实现，最小二乘法(least squares analysis)是一种 数学 优化 技术，它通过 最小化 误差 的平方和找到一组数据的最佳 函数 匹配。 最小二乘法是用最简的方法求得一些绝对不可知的真值，而令误差平方之和为最小。(least squares fitting round vc realized, least-squares method (least squares analysis) is a mathematical optimization techniques, It error by minimizing the square and a group of data to find the best matching function. Least-squares method is the most simple method to derive absolutely true value unknown, and so the sum of squared errors to the minimum.)
