SuperPixel

说明：  基于bp神经网络的车牌识别，运行时先运行nn.进行训练(License Plate Recognition Based on BP Neural Network)

非负矩阵分解法，这一种新型的子空间分解方法，增加了非负性约束，比PCA、ICA更有效(Non-negative matrix factorization method, which a new type of sub-space decomposition method, an increase of non-negative constraint, compared with PCA, ICA is more efficient)

说明：  图像处理；直方图；matlab自带函数和自己写的函数(Image processing; histogram; MATLAB functions and their own written functions)

Canny算子的分步骤实现，基于C语言，一共6部分，学习图像处理参考(Canny operator steps to achieve, based on the C language, a total of 6 parts, the study of image processing reference)

用画笔绘制圆角矩形，椭圆，饼形，并用不同颜色画刷进行填充。(Draw a rounded rectangle, ellipse, pie with a brush, and brush with a different color fill.)

说明：  图像的DCT变换 提取高频分量 和低频分量 (DCT change)

视频读取并提取目标背景 背景要求是静止的 效果很好(Video read and extract the target background static background requirements are well)

小波包分解，求能量程序，，对小波包的了解掌握都很有用，希望对读者游泳(the wavelet packet decomposition and energy distribution )

基于相位相关的图像配准，图像的移动参数代码(Phase correlation-based image registration, image of the movement parameter code)

说明：  1、正弦函数 f (t) = K sin(wt +a) 2、矩形脉冲函数 f (t) = u(t) - u(t - t0 ) 3、抽样函数 4、单边指数函数 f (t) = Ke -t 5、已知信号 f1(t) = u(t + 2) - u(t - 2)， f 2 (t) = cos(2pt) ，用 MATLAB 绘制 f1(t) + f 2 (t) 和 f1(t)′ f 2 (t)的波形。(such as : Sine function f (t) = K sin(wt +a) Rectangular pulse function f (t) = u(t)-u(t-t0) Sampling function One-sided exponential function f (t) = Ke -t Known signal f1(t) = u(t + 2)-u(t-2), f 2 (t) = cos(2pt), draw with MATLAB The waveforms of f1(t) + f 2 (t) and f1(t)*f 2 (t))
