A Modified SURF Descriptor and Its Application in Remote Sensing Images Matching

A modified Speeded-up Robust Features(SURF) descriptor based on Haar-like features,line features and diagonal features are added in the descriptor is proposed.Integral images allow fast computation,and are used for matching with SURF.However,the SURF descriptor has a lower discriminating ability when compared with SIFT.Experimental results demonstrate that the modified descriptor has a better discriminating ability compared with SURF descriptor.
