Abstract |
Background |
Neutrosophic based methods are becoming very popular in denoising of images due to the capability of handling indeterminacy. The main goal of denoising is to maintain balance between edge preservation and speckle reduction.
Methods |
To achieve this, neutrosophic based total variation method using Nakagami statistics have been explored to develop an efficient speckle reduction method. The proposed Neutrosophic based Nakagami Total Variation (NNTV) method initially transforms the image into the neutrosophic domain and then employs the neutrosophic filtering process for speckle reduction. The NNTV quantifies the indeterminacy of image by determining the entropy of indeterminate set.
Results |
The performance of the proposed method has been evaluated quantitatively by quality metrics on synthetic images, qualitatively using real thyroid ultrasound images through visual examination by medical experts and by Mean Opinion Score.
Conclusion |
From results, it has been observed that NNTV method performed better than other speckle reduction methods in terms of both speckle suppression and edge preservation.

Highlights |
• | The Neutrosophic based Nakagami based Total Variation (NTV) method has been proposed. |
• | It can make balance between speckle reduction and edge preservation. |
• | It is able to handle the indeterminate pixels and preserve the valuable information such as texture and edges. |
• | It can assist endocrinologists in improving the quality of ultrasound images for accurate segmentation of thyroid nodules. |
