ON IMAGE MOSAIC ALGORITHM IN AIRBORNE INFRARED IMAGING SYSTEM FOR MARITIME SEARCH AND RESCUE
摘要
Abstract
Because of the complicacy of SIFT feature point descriptor,it will result in more image stitching time.In view of this,we propose a fast infrared image mosaic algorithm.This algorithm extracts the key frames from a sequence of infrared image first,and then preprocesses the image distortion and the sea clutter.In order to shorten image stitching time,this algorithm limits the feature point extraction area between two adjacent images.Finally,it uses bilateral matching method to improve the registration accuracy,and uses Gaussian linear weighting fusion algorithm to get a seamless image.Experimental results prove that the algorithm improves the stitching speed,and when the feature points are not many,the improved SIFT matching algorithm can reach the ideal real-time effects.关键词
