Abstract EN
We propose a novel filtering technique capable of reducing the multiplicative noise in ultrasound images that is an extension of the denoising algorithms based on the concept of digital paths.
In this approach, the filter weights are calculated taking into account the similarity between pixel intensities that belongs to the local neighborhood of the processed pixel, which is called a path.
The output of the filter is estimated as the weighted average of pixels connected by the paths.
The way of creating paths is pivotal and determines the effectiveness and computational complexity of the proposed filtering design.
Such procedure can be effective for different types of noise but fail in the presence of multiplicative noise.
To increase the filtering efficiency for this type of disturbances, we introduce some improvements of the basic concept and new classes of similarity functions and finally extend our techniques to a spatiotemporal domain.
The experimental results prove that the proposed algorithm provides the comparable results with the state-of-the-art techniques for multiplicative noise removal in ultrasound images and it can be applied for real-time image enhancement of video streams.
