Published online Oct 8. ACM Transactions on Graphics. Numerical results obtained for the static images are summarized in Table 1. Another approach is to determine the similarity function ulteasound pixels x and x i by all possible paths connecting them Figure 2. SearchWorks Catalog Stanford Libraries.

The video denoising algorithms were tested using publicly available video sequences: Such technique should be capable of real-time processing.

The source codes of the algorithms used in our comparison were provided by the authors of the respective papers. Additionally, the proposed filter gives better results for synthetic images. University of Illinois Press; A visual comparison of the results achieved for the phantom image is drawn in Figure 9. Computer Methods and Programs in Biomedicine. Withoutabox Submit to Film Festivals. The proposed filtering techniques were designed for multiplicative noise suppression, specifically for ultrasound image and video filtering.

The proposed algorithm is based on despckle idea of spatial digital paths presented in [ 2021 ]. Image Processing On Line. Abstract 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.

The authors declare that there is no conflict of interests regarding the publication of this paper. In our work, the simplified speckle noise model has been employed, since it has been applied successfully in many studies [ 11242829 ]. The proposed filter is also more stable algoritnms a wide range of input parameters and gives satisfactory results in terms of different quality metrics and visual inspection.

From this figure, it can be seen alhorithms most filters removed multiplicative noise and produces more visually pleasing results, but the outcomes are slightly blurred. The assessment of the achieved results can be also evaluated by segmentation accuracy applying image denoising as the preprocessing step, but currently, it is out of scope in this work.

In this case, the similarity function takes the form as follows:. Speckle reducing anisotropic diffusion. The proposed ultrasound data seems to be more reliable, due to the fact that it contains artifacts typical for an ultrasound acquisition process and thus it can be used for image quality evaluation. Table 2 summarizes results obtained for the set of test video sequences. Additionally, the efficiency of the proposed denoising framework is strongly connected with the type of digital paths.

The next stage is a normalization of the similarity function, which can be defined as follows:. This necessitates the need for robust despeckling image and video techniques for both routine clinical practice and tele-consultation.

Similarity Functions Weights for the filter described by 2 can be defined in many ways; in our case, we use two different approaches based on connection costs calculated along digital paths. Publication date Series Synthesis lectures on algorithms and software in engineering ; 1 Note Part of: This necessitates the need for robust despeckling techniques for both routine clinical practice and teleconsultation. The new denoising scheme explores spatial or spatiotemporal pixel neighborhood in order to calculate the filter weights i,aging pixels belonging to the processing window.
