说明：  一个基于样例的图像修补技术的matlab演示(A sample-based image repair technology demo matlab)

利用MATLAB编程实现车牌号识别并显示，并对出入库时的车辆时间进行记录，计算车辆在停车场的时间(The license plate number is identified and displayed by MATLAB programming, and the vehicle time is recorded and the time of vehicle in the parking lot is calculated.)

图像 自动 标注 通过分析 训练集 ，学习 图像 和标注词 之间的关系，得出 之间的关系，得出 一些规则， 然后使用这些规则 自动 推导出 图像 最适合的标注词 ，这些标注词代表了图像的 ，这些标注词代表了图像的 高层 语义信息 。(Automatic image annotation by analyzing the training set, learning image and mark the relationship between words, the relationship between the draw, draw some rules, and then use these rules to automatically derive the most suitable image annotation words, these words represent the image annotation , these words represent the image annotation level semantic information.)

对图像做spca有监督的主成分分析降维，并投影回图像来降噪，在本程序中，使用正弦函数控制图像变化，函数值作为监督信息(Image do spca supervised principal component analysis dimension reduction, noise reduction and projected back images)

说明：  识别指纹端点分叉点以及奇异点，其中还包括指纹方向场和指纹梯度场的计算(It also includes the calculation of fingerprint direction field and fingerprint gradient field)

高斯平滑滤波实例，高斯滤波实质上是一种信号的滤波器，其用途是信号的平滑处理，我们知道数字图像用于后期应用，其噪声是最大的问题，，由于误差会累计传递等原因，很多图像处理教材会在很早的时候介绍Gauss滤波器，用于得到信噪比SNR较高的图像（反应真实信号）。 (Instance of the Gaussian smoothing filter, Gaussian filter is essentially a signal filter, its purpose is to smooth processing of the signal, we know that the digital image for the late application, the noise is the biggest problem, the error accumulated transfer reason, a lot of image processing textbooks will be introduced at an early Gauss filter for higher SNR of the image (real response signal).)

maximally stable extremal regions matlab codes use to detect maximally stable extremal regions.

小波包程序2，能够对信号进行特征提取，有利于初学者。(This is a wavelet packet program 2，which is useful for the beginners.)

本例程序包含OMP、SP、IRLS、CoSaMP等重构算法，比较性能优劣。(The example application consists of OMP, SP, IRLS, CoSaMP reconstruction algorithm, and compare performance advantages and disadvantages. )
