逆透视变换的数学原理，在文档中有详细的逆透视变换的矩阵推导过程，但是没有代码，opencv逆透视变换代码可以看我发的另一篇资源。。。。。。。。。。。。。。。。。。(The mathematical principle of reverse perspective transformation, in the document there is a detailed matrix rendering process of the inverse perspective transformation, but there is no code, opencv reverse perspective transformation code can see another resource I sent)

说明：  超像素实现图像分割，可以实现彩色图像分割(An EM algorithm is used for image segmentation.)

说明：  LSCN彩色图像增强算法，PCNN算法的优化改进(algorithm of LSCN color image enhancement)

图像几何变换（缩放、旋转）中的插值算法 ( The picture geometry transformation (缂╂斁, revolves) the center interpolation algorithm )

说明：  facet边缘检测的matlab源代码,是基于二阶模型，只要运行最后一个hhh.m就可以了(facet Edge Detection Matlab source code is based on second-order model, as long as the last one run on the hhh.m)

这是一个灰度图像进行哈夫曼编码的Matlab程序，包括编码和解码部分。绝对能用！(Huffman Code)

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)

实现在图像背景上叠加 下雨 下雪 的效果(Achieve in the BMP image background superimposed rain, snow effect)

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))

It initializes the entire image processing. The simulation parameters can be changed in this main file.
