说明：  编程实现灰度图像的频域滤波算法。使用Matlab实现不延拓和延拓两个版本。对于延拓和不延拓版本，在理想低通滤波器、巴特沃斯低通滤波器和高斯低通滤波器上比较两者的区别；对于延拓版本，比较不同参数设置对上述三种滤波器滤波结果的影响。(Program to realize the filtering algorithm of gray image in frequency domain. Matlab is used to realize two versions of no extension and extension. For the extension version and the non extension version, the differences between the ideal low-pass filter, Butterworth low-pass filter and Gauss low-pass filter are compared; for the extension version, the effects of different parameter settings on the above three filter results are compared.)

sar滤波中最经典的频率域滤波算法.效果也不错.(sar filtering of the most classic frequency domain filtering algorithm. effect is not bad.)

一个基于matlab的车牌定位的原程序.可以实现精确的车牌定位。(a Matlab-based positioning of the license plate of the original procedure. Can achieve precise positioning of the plates.)

完成水果的尺寸形状表面缺陷的判别，BP神经网络的训练判别表面缺陷(Fruit size, shape and surface defects are identified. BP neural network is used to identify surface defects.)

图形学中的透视投影算法 在屏幕中心绘制立方体的透视投影 可以绘制一点透视图 二点透视图 三点透视图(Graphics in the perspective projection algorithm for drawing a cube in the center of the screen you can draw a little perspective projection perspective two point perspective three-point perspective)

可以采用形态学方法找出边界，比较有益的初学者的学习方法。(It s very good for a newer to learning about image processing.)

说明：  将原图二值化处理后，对二值图像进行腐蚀处理去掉图中主体以外的噪点或小斑迹(After binarization of the original image, the binary image is corroded to remove the noise or small spots outside the main body of the image)

空域可视水印算法（matlab实现）， 考虑了HVS特性，可见水印嵌入同时考虑了原图像和水印图像视觉特性。(airspace visual watermarking algorithm (Matlab achieved), in consideration of HVS features embedded watermark can be seen taking into account the original image and a watermark image visual characteristics.)

数学形态学去噪 有效地还原了原始信号 去除了振动噪声和基线漂移(signal denoising )

实现了图像的rgb格式与lab格式的互相转化，方便大家在lab空间中处理图像(Achieved rgb image format and transform lab format to facilitate processing in the lab space images)
