Comparison of several speckle reduction techniques for 3D ultrasound images

摘要

In this paper, we describe three speckle reduction filters and compared their performance in speckle reduction for 3D ultrasound images. Filtering techniques related to those filters include Frost's filter, anisotropic diffusion, Normalized bilateral filtering, and non-local means filter. The qualitative as well quantitative evaluations are used to analyze the performance of four filters.
