Contourlet域的多极化SAR图像自适应融合方法
Adaptive fusion method for multi-polarization SAR images in Contourlet domain
摘要
Abstract
In consideration of the fusion of multi-polarization SAR images, this paper proposes a method of adaptive window image fusion based on Contourlet transform. In this scheme, the original image is Contourlet transformed at first, the image is decomposed into a low frequency (LF) sub-band and a few high frequency (HF) sub-bands on various directions, and then the decomposed LF sub-bands are fused in the weighting of neighborhood energy, next, the adaptive adjusting fusion window method could be used for HF sub-bands on each direction, which id adaptive to the change of speckle noise characteristics of SAR image. By doing the fusion experiments on bi-polarization SAR images and comparing with Wavelet transform and other fusion results, it is shown that the images fused by this proposed method could achieve the better effect in terms of visual characteristics and the statistical factor of objective evaluation, and the fused images could provide more abundant information than that of the originals.关键词
