Contrast Stretching in Matlab

基于visual c++平台，相机标定方法中的直接线性变换方法，即DLT方法(Based on visual c++ platform, camera calibration method of direct linear transformation method, namely DLT method)

通过Gabor原子库对语音信号进行处理，用到匹配追踪算法，对各种语音信号的仿真实验都很成功。(Gabor atoms is through the voice signal processing, matching pursuit algorithm is used, on the simulation of various audio signals are successfully.)

Canny边缘检测算法,canny算法计算梯度,并从小波模极大重构图像.(Canny edge detection algorithm, canny algorithm for calculating the gradient, and from the Wavelet Modulus Maxima Image Reconstruction.)

说明：  有四个M文件，可以用于图像处理中的图像细化，有较好的效果(There are four M documents, can be used for image processing of image thinning, there are good results)

这是图像校正程序，matlab运行环境，是我自己编的，可能没那么完美，还要有改进的地方(This is the picture calibration procedures)

车道线检测，实验代码，本人已经验证过，可以直接使用，带有图片和实验结果(The lane line detection code)

可以将连续图片转换成视频文件，值得参考学习(Convert a continuous image into a video file)

说明：  matlab图像去模糊算法代码，使用两倍长度的点扩散函数进行维纳滤波，模糊图像加入随机噪声，计算噪声信号功率比，使用噪声能量和图像一维自相关函数进行维纳滤波，模糊后的图像，减小噪声能量进行规则化滤波，增大拉格朗日乘子进行滤波，继续对恢复的图像反卷积，产生模糊图像，最初的PSF，显示最初PSF下恢复的PSF。(MATLAB image deblurring algorithm code, using double-length point spread function for Wiener filtering, adding random noise to blurred image, calculating noise signal power ratio, using noise energy and image one-dimensional autocorrelation function for Wiener filtering, blurred image, reducing noise energy for regular filtering, increasing Lagrange multiplier for filtering, continue to restore the image. Like deconvolution, a blurred image is generated. The original PSF displays the restored PSF under the original PSF.)

强大的小波包分析程序，将信号分频分析，在感兴趣的频率域内抽取信号信息。(Powerful wavelet packet analysis procedures, the signal of frequency analysis, frequency domain of interest extracted signal information.)
