ImageProcessing--Contrast-Stretching-with-Matlab

检测交通视频中的汽车，运行环境必须是matlab2009a以上版本，里面有程序和测试视频(car detect with matlab)

this codes are not so important but they are useful to learn matlab signal processing

matlab带通滤波程序 两个滤波器都是切比雪夫I型数字滤波器，不是巴特沃尔滤波器，包括实例 (bandpass filtering matlab program)

提供數種回響演算法.利用6個平行的comb濾波器達成擬真的回響效果(Provides several reverberation algorithms. Use 6 parallel comb filter to achieve realistic reverb)

说明：  单相电弧炉，简单易懂 可以直接2016b打开(Single-phase arc furnace, simple and easy to understand, can be opened directly in 2016b)

说明：  禁忌（Tabu Search）算法是一种亚启发式(meta-heuristic)随机搜索算法，它从一个初始可行解出发，选择一系列的特定搜索方向（移动）作为试探，选择实现让特定的目标函数值变化最多的移动。为了避免陷入局部最优解，TS搜索中采用了一种灵活的“记忆”技术，对已经进行的优化过程进行记录和选择，指导下一步的搜索方向，这就是Tabu表的建立。(Tabu Search algorithm is a meta-heuristic random search algorithm. It starts from an initial feasible solution, chooses a series of specific search directions (movement) as a trial, and chooses to achieve the movement that makes the most changes in the value of a specific objective function. To avoid falling into local optimum, TS search uses a flexible "memory" technology to record and select the optimization process that has been carried out, and to guide the next search direction, which is the establishment of Tabu table.)

稀疏分解信号重建程序，利用匹配追踪原理不断对信号匹配，最后达到重建信号目的。(sparse decomposition signal reconstruction procedures, the use of matching principle constantly tracking the signal matching, Finally signal to the redevelopment purposes.)

matlab的gscale函数功能是将强度图像等映射到别的值范围(Function of matlab gscale intensity image is mapped to a different range of values, etc.)

Tikhonov正则化工具箱，可实现病态方程组的正则化，以及采用L曲线法、岭估计法、GCV法等确定正则化参数，内含使用方法，亲测有效。(Tikhonov regularization toolbox, which can realize regularization in morbid equations, and using the L curve method, ridge estimation, GCV method to determine the regularization parameter, embedded application method, effective measurement.)

matlab的GUI实现一个加法器，同时使用mcc编译成了exe的可执行文件，非常适合初学者(matlab GUI implementation is an adder while using mcc compiled into exe executable file, very suitable for beginners)
