摘要：
Underwater sonar imaging is a significant means for a variety of maritime work. However, the sonar images are corrupted by signal dependent speckle noise, which restricts the potential practical applications. In this paper, we propose a novel variational approach that addresses the adaptive sonar image denoising problem. To accurately describe the signal dependent characteristic of noise for real sensors, we utilize a generalized noise model, which can be adapted to represent various types of noise. With the generalized noise model, we formulate the denoising problem via a variational approach...
