An intelligent digital image mosaics system structure is conceived to deal with the difficult problems of large data amount and long time consuming in Dunhuang fresco digital image mosaics.A new algorithm based on SURF for image registration is presented.It is a fast computation based on the integral image through the Fast-Hessian detector,the feature points are extracted.For each feature point,the dominant orientation is assigned by computing Haar-wavelet responses,and then the descriptor is generated.Image matching is made based on Euclidean distance between these descriptors.At last,the original image and reference image are fused together by gradating in-and-out amalgamation algorithm.Experimental result shows that this system can not only meet the requirement of accuracy,but also has a small data amount and fast speed for image mosaics.
