Abstract

Image change detection is a process in which two or more images of same scene that are captured at two different time instants are taken and changes are detected. Out of many categories of images, detection of changes in Synthetic Aperture Radar (SAR) images is a critical task because of the speckle noise present in these images. In this paper changes are detected in SAR images based on an image fusion strategy and fuzzy clustering algorithms. Image fusion is used to generate a difference image from the information obtained from mean ration and log ratio operator and Stationary Wavelet Transform (SWT) is used to decompose the sub bands and the two clustering algorithms namely fuzzy local information C means clustering (FLICM) algorithm and reformulated fuzzy local-information C-means clustering algorithm (RFLICM) are considered which are applied on the fused image and the changed and unchanged areas are differentiated by forming clusters of similar and dissimilar elements. Experiments are carried out on the different images by applying FLICM and RFLICM algorithms.
