一个简单圆，有圆心半径，已知半径，求周长和面积。已知某点求是否在圆上。(A simple circle, a circle radius, known radius, strives for the pupil. Known to some point whether in the round.)

根据paper思想，自己编写的SPIHT编解码。可以处理不同图像大小的小波系数，严格按照paper中的算法编写。细节见说明文档(under the paper thinking, their preparation SPIHT codec. Image can handle different sizes of the wavelet coefficients and strictly according to the paper prepared algorithm. For details, see the documentation)

对灰度图像或RGB图像，进行基于边缘检测和区域生长的图像分割技术(On grayscale images or RGB images, for edge detection and region growing-based Segmentation)

对图像进行平滑去噪，提高图像的质量，为后期的图像处理打基础(very good)

说明：  有雾天气下图像清晰化方法研究 图象增强的各种方法 内含程序(Foggy weather images clear method of image enhancement program includes a variety of methods)

关于脆弱性水印的，是一个挺不错的。希望能帮助到有需要的同学(on vulnerability watermark is a quite good. Intend to help the needy students)

说明：  该代码的主要功能是图像边缘检测，利用霍夫变换确定圆的位置，并进行缺陷定位着色等操作(The main function of the code is image edge detection, using HOF transform to determine the location of the circle, and the location of defects such as coloring operations)

用水线阈值法分割图像：通过对图像进行高帽、低帽变换，并将得到的结果进行相减，可以增强图像，然后利用分水岭算法就行分割！(Water line thresholding segmentation image: The image of flattery, low cap transformation, and will be the results of subtraction, it can enhance image, and then use the watershed segmentation algorithm on the line!)

压缩传感理论，用K-SVD算法训练字典，过完备字典(Compression sensing theory, SVD algorithm with K- had complete training dictionary, dictionary)
