An Algorithm for Medical Ultrasound Image Enhancement by Speckle Noise Reduction
Medical digital images and medical image processing represent an important subfield in computer vision. Different algorithms and methods for analysis and improvement of various medical images were proposed in the past years. One important research topic is improvement of ultrasound images. In this paper we propose a modified median filter with adaptive size for removing one of common noise in ultrasound medical images, speckle noise, including the case when spots are larger than one pixel. Proposed method was tested on different ultrasound images and different evaluation metrics used as measure of the quality of noise removal have shown that the proposed method was successful. Key Words: Ultrasound medical images, speckle noise, denoising, median filter.
