C# 实现验证码识别

说明：  WAV音频的MATLAB读取以及傅里叶变换作频谱图(WAV Audio Reading by MATLAB)

高斯滤波算法，可用于模糊图片，除掉图片中的高频噪声(gauss fliter to remove high frequency noise for pic )

6Improved discriminate analysis for high dimensional data and its application to face recognition. 2007-Zhuang-Dai.pdf

说明：  二进小波变换的图像增强,matlab代码(Dyadic wavelet transform image enhancement, matlab code)

特征提取是图像配准的重要步骤，使用Harris角点检测算法实现图像拼接。(Feature extraction is an important step in image registration, using Harris corner detection algorithm for image mosaic.)

一种基于形貌特征识别圆形的方法，通过拟合圆方程来实现的经典hough变换方法(A method of Circle Recognition Based on morphological features is introduced. The classical Hough transform method is implemented by fitting the circle equation.)

可以打开各种图像格式，并显示，很好很强大(Can open a variety of image formats)

计算局部形状描述符梯度方向直方图（HOG），直接输入图像即可用。(Calculate the local shape descriptors gradient orientation histogram (HOG), the input image can be used directly.)

适合各类图象， 手动选择感兴趣目标区域，使用于图象图象处理，同时包含一区域生长程序。(Suitable for all types of images, manually select the target region of interest, the use of image processing in the image at the same time contains a region growing procedure.)
