JPEGCompression

用c语言编写的数字图像处理程序，图像读取，图像增强，图像复原，傅里叶变换，离散余弦变换都有(With the c language digital image processing, image scanning, image enhancement, image restoration, Fourier transform, discrete cosine transform has)

surf特征提取算法，较sift优良，包括示例和实验图片，还有算法原文(surf feature extraction algorithms, the more sift fine, including examples and experimental images, as well as the original algorithm)

基于JPEG压缩的无参考图像质量评价算法，输入一幅图像，输出图像的评价值，值在0-100之间，越接近0图像的质量越好(JPEG-based compression algorithm for no-reference image quality assessment, an input image, the output image uation value, a value between 0-100, closer to 0 the better the image quality)

利用多用方法进行数字图像去模糊实例，便于初学者理解反卷积去模糊、伪逆去模糊等基本算法(Example scripts for image debluring, try to give general introduction of some basic algorithms, such as pseudo inverse debluring.)

利用梯度插值算法实现图像的去马赛克，图像质量大大提高(Using gradient interpolation algorithm to achieve image mosaic, image quality is greatly improved)

matlab的gui设计程序,有关<信号与系统>课程的辅助教学设计(Matlab GUI design, the relevant & lt;)

说明：  一个机载SAR的成像算法，SAR的点目标RD成像算法(An airborne SAR imaging algorithm, SAR point target imaging algorithm RD)

改进后的非线性各向异性扩散用于图像中的保边去噪，增加了二阶导数，是滤波效果更好(Improved nonlinear anisotropic diffusion for edge preserving image denoising, an increase of second derivative, is a better filtering effect)

首先生成如下形式的图片：图中的白条为7象素宽，210象素高，白条间的宽度为17象素。 应用多种滤波器进行处理：算术均值，几何均值，谐波均值，逆谐波均值，中值滤波，中点滤波，最大值、最小值滤波等。注意，需改变模板大小。详细比较上述的结果，并分析原因。 (First generation following form images: figure IOUs 7 pixels wide, 210 pixels high, the width is 17 pixels between IOUs. Using a variety of filters for processing: the arithmetic mean, geometric mean, harmonic mean, inverse harmonic mean, median filtering, filtering midpoint, maximum, minimum filtering. Note that the need to change the template size. A detailed comparison of these results and analyze the reasons.)

这个是最成熟的人脸检测算法viola-jones的matlab版本实现，适合搞研究的同学们(a matlab implementation of the viola-jones face dection!)
