This letter presents a new method for airport detection from large high-spatial-resolution IKONOS images. To this end, we describe airport by a set of scale-invariant feature transform (SIFT) keypoints and detect it using an improved SIFT matching strategy. After obtaining SIFT matched keypoints, to both discard the redundant matched points and locate the possible regions of candidates that contain...
There have been many approaches to recognize bridges, but most of them can not be effectively used on real-time occasions. In this paper, a novel approach is presented to rapidly recognize bridges over water in large remote sensing imagery. First, the rough river regions are quickly detected based on fuzzy pattern classification and clustering analysis. Next, with the knowledge of relationship between...
