基于协同分割的高分辨率遥感图像变化检测
Change detection from high-resolution remotely sensed images based on cosegmentation
摘要
Abstract
Due to the inconsistency of multi-temporal objects’boundaries for object-based change detection,this paper proposes a new change detection approach from multi-temporal high-resolution remotely sensed images based on the concept of cosegmentation in the filed of computer vision.First,multi-temporal remotely sensed images are co-processed to discover the change feature and a map of change intensity is obtained using the magnitude of spectral change between images.Then cosegmentation is performed under the guidance of the change intensity map, combined with each image features.Multi-temporal change objects with accurate boundaries and spatial correspondence are directly generated by energy function minimization finally.Experimental results obtained on multi-temporal aerial images show that multi-temporal change objects are preferably segmented and the change process can also be clearly acquired through establishing a correspondence between multi-temporal change objects. This novel method can provide a workable way for object-based change detection from high-resolution remotely sensed images.关键词
