摘要

斑点噪声是超声图像的固有特性，它使图像的解释变得困难，因此是不可取的。在这项工作中，研究了Savitzky-Golay滤波器在超声图像中的斑点减少。该滤波器针对不同的顺序和帧长度进行了测试。在一定的滤波器阶数和帧长范围内，通过分析滤波器的性能，启发式地选择最优阶数和帧长。该方法在合成图像和临床超声图像上进行了测试，取得了良好的效果。

Investigation of Performance of Savitzky-Golay Filter for Speckle Reduction in Ultrasound Images

Speckle noise is inherent nature of ultrasound images which makes interpretation of the images difficult and hence is undesirable. In this work, Savitzky-Golay filter is investigated for speckle reduction in ultrasound images. This filter is tested for different order and frame lengths. Optimal order and frame length is chosen heuristically by analyzing performance of the filter for a range of filter order and frame length. The method is tested on synthetic images as well as clinical ultrasound images and promising results are achieved.
