Abstract: This study transferred Gauss two order differential template and convolution operation of image function to the integral image subtraction of Box filter.At the same time,the dimension of feature vectors of feature detection operator was decreased through introducing SURF operator.The computational complexity of SIFT algorithm and image matching time were reduced.This study solved the problem that UAV sensing image matching requires high real-time.The simulation shows the improved SIFT algorithm accelerates the operation speed with the same rubustness and matching rate as original algorithm.

Key words: UAV,Remote sensing image,Improved SIFT algorithm,Image registration
