本方法的种子点选取采用Harris角点法，阈值则通过云模型获得，对lena图像进行了较好的分割(The method selected seed points using Harris corner point method, the threshold is obtained through the cloud model, for better lena image segmentation)

说明：  也是水平集方法的一个matlab源代码 基于边缘信息的(level is a collection of source code based on Matlab Edge Information)

说明：  不管对于图像的编码还是解码，三次样条算法的性能都是很好的，然后由于计算量比较大使他的效率有所下降，在次提出了一个考虑算法质量的前提下的快速算法。(regardless of the coding for images or decoding, cubic spline algorithm performance are good, and then because of the comparison calculation of the efficiency Ambassador he declined, in a meeting of the algorithm to consider the quality of the fast algorithm.)

产生运动模糊图像以及逆滤波，维纳滤波的恢复效果比较(Produce motion-blurred images, as well as inverse filtering, Wiener filtering effect of the restoration of)

NIPS2006论文“Saliency based on Information Maximization”的源码，用于显著图计算，作者是N. Bruce 和 J.Tsotsos (a code for "Saliency based on Information Maximization",N. Bruce &J.Tsotsos ,NIPS,2006)

局部拉普拉斯滤波代码，效果很好，可以直接运行(Edge-aware Image Processing with a Laplacian Pyramid)

自适应门限二值化图像处理，自己最近完成的，还可以用，文件也加了两张图的效果，需要的可以试一试(Adaptive threshold binarization image processing, recently completed its own, but also can be used, the document also increase the effectiveness of the two plans, the needs may try it)

曲面拟合法是一种高精度、计算量小、抗噪性能强的方法，当前已被广泛地应用于 各种场景。比如岩石材料的变形测量、电子器件变形的测量、基于掌纹图像相关匹 配的重复定位技术等。曲面拟合法能够成功计算出亚像素位移的前提是整像素搜索阶 段可以正确搜索出模板的整像素匹配点，一旦整像素匹配点搜索出现错误，那么亚像素 测量阶段所得到的位移距离就会失去意义。 使用不同的拟合函数对相关系数矩阵进行曲面拟合，会对结果产生一定的影响，比 较常用的拟合函数有二次函数、三次函数、高斯函数等。(Surface fitting method is a high-precision, computational complexity is small, strong anti-noise performance method, has been widely used in various scenes. For example, deformation measurement of rock materials, deformation measurement of electronic devices, and repetitive location technology based on palmprint image correlation matching. Surface fitting method can successfully calculate the sub-pixel displacement on the premise that the whole pixel search stage can correctly search the template of the whole pixel matching point, once the whole pixel matching point search error, then the sub-pixel measurement phase of the displacement distance will be meaningless. Using different fitting functions to fit the surface of the correlation coefficient matrix will have a certain impact on the results. The commonly used fitting functions are quadratic function, cubic function, Gaussian function and so on.)

数字水印程序，包括多分辨嵌入水印、提取水印程序，盲水印嵌入、提取程序，以及滤波攻击和JPEG攻击程序，PSNR和相似度计算公式（MATLAB）(digital watermarking procedures, including multiresolution embedded watermark, watermark extraction procedure, blind watermark embedding and extraction procedures, Filtering and attack and attack JPEG procedures, PSNR and the similarity calculation formula (MATLAB))

本代码是使用matlab编写的harr特征的代码，值得大家研究和参考(This code is the use of matlab prepared harr characteristics of the code, it is worth study and reference)
