This applicationnot only demonstrates the basics o...

MATLAB produces barrel distortion and correction procedures

For any one picture, a program that is barrel distortion, another could be restored to its normal picture, amend the symbol will become a Pincushion distortion, notes....

Use Codebook algorithm for moving object detection

This code is based on the codebook algorithm of the  paper"Real-time foreground–background segmentation using codebook mode", implemented on C++ platform, use opencv 2.3.1 version, realized the moving object detection. CodeBook algorithm of the time series model of the basic idea is...

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...

Point cloud border generation algorithm

Given a set of n points, build its borders (not necessarily convex boundary) is commonly used in graphics processing method. This procedure using a rolling ball, and connecting points boundaries, and generates an enclosing polygon containing all the points....


       VisualSFM is a GUI application for 3D reconstruction using structure from motion (SFM). The reconstruction system integrates several of my previous projects: SIFT on GPU(SiftGPU), Multicore Bundle Adjustment, and Towards Linear-time Incremental Structure from Motion. Visua...


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...
