A PDE based Model for Sonar Image and Video Denoising

A PDE model for reducing the speckle noise from ultrasound video sequences is proposed in this article. A spatial approach is used for video denoising. First, a continuous differential mathematical model for noise removal is proposed. Then, a discretized variant of the denoising approach is described. The proposed PDE based technique is successfully applied to sonar images and videos.
