基于第二代Bandelets变换的SAR图像稀疏表示

摘要

Bandelets变换是一种基于边缘的图像表示方法，能够自适应的跟踪图像的几何正则方向，能对平滑的自然图像进行有效的稀疏表示。SAR图像具有相当丰富的纹理细节信息，本文将应用第二代Bandelets变换对SAR图象进行稀疏表示，并进行重建效果对比。%Bandelets transform is a method based on the edge of the image representation,can implement an adaptive approximation of image geometry.SAR images consist of textures, this paper wil use the second generation Bandelets transform for Sparse representation of SAR images and rebuliding.
