摘要

本文对各种超声图像去噪技术进行了研究，并对不同条件下的结果进行了比较。合成孔径雷达图像和超声波图像经常受到散斑噪声的破坏。它也被称为颗粒噪声。消除散斑噪声的方法有很多。该滤波器是为去除散斑噪声而开发的。本文综述了用于去除散斑噪声的滤波器。定义了频率分析方法、各种自适应方法、时间分析方法来去除散斑噪声。

Investigation of various Speckle Noise Denoising Filters

In this paper, various ultra sound image denoising techniques are investigated and results are compared for various conditions. Synthetic Aperture radar images and ultra sound images are often corrupted by speckle noise. It is also known as granular noise. There are many methods for removal of speckle noise. The filters are developed for the removal of speckle noise. This paper reviews filters mostly used to remove speckle noise. Frequency analysis methods, various adaptive methods, temporal analysis methods are defined for the removal of speckle noises.
