Evaluating SAR images based on the statistic characteristic of the wavelet coefficients

Abstract

In order to assess SAR image, it is essential to discriminate speckle noise and signal properly. This paper proposes a new technical specification, wavelet-based fuzzy signal-to-noise ratio (WF-SNR) for evaluating SAR image. This idea roots from the techniques of denoising by shrinking the wavelet coefficients. The resolution of SAR image is used to modify… (More)
