Image_Filtering

自编语谱图函数，可实现基本的spectrogram功能(Self compiled spectral function, which can implement basic spectrogram functions)

说明：  输入灰度图像，采用pcnn算法进行边缘检测(Input gray image, use PCNN algorithm for edge detection)

此程序为袁晓彤CVPR论文“基于多任务联合稀疏表示的的视觉分类”的主代码部分(The program for Yuan Xiaotong CVPR paper " visual classification with Muti-task joint sparse representation" main code of the parts)

数字图像处理中图像的增强方便的源代码，包括图像灰度修正，图像的平滑，中值滤波，图像的锐化，伪彩色和假彩色的增强等(Digital image processing image enhancement convenient source code, including the gray correction, image smoothing, median filtering, image sharpening, pseudo-color and false color enhancement, etc.)

指纹图像与处理源码及资料，包括图像滤波、方向场计算、频率图计算等(source code and papers of fingerprint preprocessing methods)

将源图像做高斯卷积，以光滑化源图像，用于图像的预处理(source image makes convolution with gauss so as to smooth the image as a preprocess.)

一些图像处理中的增强算法，一些些一些些一些些(Some of the enhanced image processing algorithms, some more some more)

一个作业,用matlab实现指纹识别，做得不好，惭愧(an operation using Matlab achieve fingerprint identification, is not done properly ashamed)

matlab函数，将多维矩阵的极值找出并定位，图像处理经常用到，很简单很好用(matlab function, multi-dimensional matrix to identify and locate the extreme, often used in image processing, it is very simple to use)
