说明：  数字识别，能识别0到9这几个数字啊，基于matlab(Digital identification, can identify it 0-9 a few figures ah, based on matlab)

人体脑信号波形检测与分析,包含自相关,功率谱分析的方法(Human brain signal detection and analysis, including autocorrelation, the method of power spectrum analysis)

Guilde Filter 图像滤波； 包含[2015]Fast Guilded filter.pdf ; [2013] Guided Image Filtering.pdf 经典。(inculde classical paper for guilded filter)

说明：  改进的canny算法，边缘处理更加精确，瘦边效果改进力度大，可以借鉴参考(The improved Canny algorithm, edge processing more accurate, thin edge effect improved greatly, can be used for reference)

这是一个简单的程序代码，主要针对hough变化(This is a simple program code, mainly for hough change)

简单起见，这里设定阈值为122，即最大灰度的一半(the sake of simplicity, this threshold value is set to 122, the largest gray half)

相机标定,Tsai 张正友算法,Matlab实现((Camera calibration, Tsai zhangzhengyou algorithm, Matlab achieve))

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))

说明：  考虑DCT阈中量化效应，采用8X8的DCT模板，选择量化步长，结合缩放因子进行图像压缩。(Considering the quantization effect in DCT threshold, we use the 8X8 DCT template, select the quantization step, and combine the scaling factor to compress the image.)

2维线性判别分析算法，可以应用于人脸识别等图像处理问题中。(2 dimensional LDA algorithm,it can be applied to face recognition and other image processing problems.)
