Abstract

Objective: In the traditional edge detection differential operators, the first-order derivative masks are easy to loss image details information, and the second-order derivative masks are more sensitive to noise. As for these problems, this paper proposes a fractional-order mask for medical image segmentation. Methods: Combining the frequency characteristic and the memorability of fractional differential, the classical first-order Sobel operator is generalized to fractional-order mode; A fractional-order differential mask is constructed for extracting the edge feature of medical images. Results: The experiment results show that compared with the integer order differential mask, the fractional-order differential mask can detect more edge details feature of the medical images, and is more robust to noise. Conclusion: Based on the global characteristic of the fractional differential, the proposed fractional-order Sobel mask can extract more image edge feature details. Experiment results show that the proposed fractional-order mask yields good visual effects for brain MRI image segmentation.
