轮廓特征提取，是图像处理中底层特征中的一个重要参数，是我硕士论文中的代码(Contour feature extraction, image processing are the underlying characteristics of an important parameter, is my master' s thesis in the code)

基于小波变换的图像融合程序，低频采用加权平均，高频采用能量最大准则。(Based on wavelet transform image fusion program, low-weighted average, using high-frequency energy is the biggest criteria.)

压缩感知图像重构的算法，直接观测原始信号（二维），最后重建(Compressed sensing image reconstruction algorithm, direct observation of the original signal (two-dimensional), and finally reconstruction)

说明：  很好的指纹识别系统 希望能帮到大家 好好加油(A very good fingerprint identification system. I hope it can help you)

检测道路边缘，利用道路的平行线特性，来检测道路所在直线。(Detect edges of the road, the road parallel to the line features to detect the road where the straight line.)

用小波变换进行图像增强，先对原始图像进行非下采样的小波分解，在对每一层的高频分解系数进行处理，得到变换后的小波系数，再进行小波重构。(Image enhancement using wavelet transform, the original image and non-sampling wavelet decomposition in the high frequency decomposition coefficients of each layer, get the wavelet coefficients after the transformation, then the wavelet reconstruction. )

wpf各种统计图展示（直方图，饼图，折线图）

说明：  实现车道线检测，运用Hough变换的原理(For the process of lane line detection, this paper first searches for the edge points of the lane line, mainly including image graying, image filtering, image edge enhancement and image binarization. Then the lane line edge line is fitted. This paper uses the Hough transform to perform a straight line fitting.)
