Abstract

Speckle noise is inherent in ultrasound images, and it generally tends to reduce the resolution and contrast, thereby，to degrade the diagnostic accuracy of this modality. Speckle reduction is very im-portant and critical for ultrasound imag-ing. In this paper, we propose a novel ap-proach for speckle reduction using two-dimensional (2D) homogeneity and direc-tional average filters. We have conducted experiments on numerous artificial im-ages, clinic breast ultrasound images and vascular images. The experimental results are compared with that of other methods and the performance is evaluated using several metrics, and they demonstrate that the proposed approach can reduce the speckle noise effectively without blurring the edges and damaging the textual in-formation. It will be useful for computer aided diagnosis (CAD) systems using ul-trasound images.
