Registration is an effective pre-processing for amounts of applications like image mosaic, mapping, remote detection, and change detection. The scale-invariant feature transform (SIFT) and block matching are two widely algorithms for registration in computer vision. However, as a result of speckle noises, the two algorithms perform unsatisfactorily on synthetic aperture radar (SAR) images. In this...
Extracting the oil spills in SAR images has been challenged by the spatial heterogeneity caused by the speckles. In this paper, we present a novel variational formulation based on the local characteristics of SAR images for CV mode. The proposed method is aimed to solve the segmentation problem caused by SAR image speckles. Compared with the traditional CV model, the performance of the improved CV...
