Savitzky-Golay filter

Filtering data using Savitzky-Golay smoothing, the principle is about getting the filtering point the n points, a total of N+1 points for fitting, and then determined using the least squares correlation coefficient, which filtering point at the end of the value. Application can be extended to two-di...


基于sift的图像复制粘贴篡改检测方法,首先提取出sift特征,这里提取的sift特征是用c++代码提取的,然后进行g2nn匹配和 凝聚层次聚类 ,最后根据仿射变换参数标出篡改区域。并用连线的方式将真实区域和复制粘贴篡改...
