Fuzzy Neartude and Information in a Non-Compact Neighborhood Based Change Detection
摘要
Abstract
A new fuzzy neartude difference image is proposed.With active contour model(ACM),flood change detection for bi-temporal SAR images is performed.The proposed method overcomes the influence on the change detection performance of the goodness-of-fit between the distribution model which the context-sensitive methods always need and the true one,and also breaks the limitation that the context-sensitive method only uses the information in a fixed size and shape neighborhood.By use of the information in a non-compact region,the proposed method improves the change detection performance and the visual effect.The experiment results on two real SAR data sets show that our proposed method is superior over other related techniques.关键词
