利用最小二乘法，可以自动实现图像中的椭圆检测并拟合出来，效果很好(Ellipse detection and fitting them to achieve)

图像质量评价指标，是这篇文章“a universial image quality index”的源代码 (Image quality evaluation, the article " a universial image quality index" of source code)

用fibonacci变换方法对图象做置乱或逆置乱，效率极高，在信息隐藏中属常用的方法之一。调用函数为f=fibonacci_t(I,r,s)，其中参数分别为I=被置乱的图像，r=置乱密钥，s=0置乱，s=1逆置乱(Fibonacci transformation method used to do on the image or inverse Scrambling Scrambling, high efficiency in the information hidden in one of the methods are commonly used. Call the function f = fibonacci_t (I, r, s), which parameters were I = have been scrambling the image, r = scrambling key, s = 0 Scrambling, s = 1 inverse Scrambling)

读取单幅envi图像格式的img图像，并将其显示出来(read img)

用于小波的图像的去噪，对于刚接触图像处理的人来说简单 易懂(For wavelet image denoising, image processing for刚接触people who are easy-to-read)

说明：  图像去噪，降低图像的噪声，提高图像PSNR(image denoise,improve the psnr of image)

基于LSB的音频水印嵌入提取算法，隐藏信息为一个文本文件(Extraction algorithm, the LSB-based audio watermark embedding hidden information into a text file)

输入控制点对，即可得到畸变校正系数。 此例中使用最近临插值。如要得到更好效果，可换用双线性或3次插值。(Input control point right, you get distortion correction factor. In this case, using the most recent clinical interpolation. To get better results, can be used for bilinear interpolation or 3 times.)

用于SAR图像的相干斑抑制，内有增强Lee滤波，增强Kuan滤波，增强GammaMap滤波算法，还有等效视数，边缘保持指数的求法(For speckle suppression of SAR images, there are enhanced Lee filtering, enhanced Kuan filtering, enhanced GammaMap filtering algorithm, and the calculation of ENL and EPI.)

基于EM-马尔科夫随机场-ICM的图像分割程序，很好的学习代码(EM-based Markov random-ICM image segmentation procedures, good learning code)
