Despeckling of Ultrasound Medical Images: A Survey
Digital image acquisition and processing techniques plays important role in clinical diagnosis. Medical images are generally corrupted by noise during their acquisition and transmission. Removing noise from the original medical image is still a challenging problem for researchers. Ultrasound imaging is widely used for diagnosis over the other imaging modalities like Positron Emission Tomography...
متن کاملA Systematic Approach for Despeckling of Medical Ultrasound Images
Ultrasound is a medical diagnostic technique that is widely used because of its low cost and capability of forming real time imaging. A major problem regarding ultrasound images is the corruption by speckle noise. In this paper, speckle noise is removed by the methods based on Hard Thresholding based on Curvelets and Spatial filtering techniques such as Sobel operator, prewitt operator, Lee fil...
متن کاملAn adaptive window hybrid median filter for despeckling of medical ultrasound images
Speckle is a random multiplicative noise which obscures the perception and extraction of fine details in ultrasound image and despeckling is necessary for better diagnosis. The main aim of despeckling is to keep the important features such as edges of the ultrasound image. In this paper an adaptive window hybrid median filter is proposed for despeckling of medical ultrasound images. In the prop...
متن کاملSurvey of Despeckling Techniques for Medical Ultrasound Images
Ultrasound imaging is the most commonly used imaging system in medical field. Main problem related to this imaging technique is introduction of speckle noise, thus making the image unclear. The success of ultrasonic examination depends on the image quality which is usually retarded due to speckle noise. There have been several techniques for effective suppression of speckle noise present in ult...
متن کاملWavelet Thresholding Techniques in Despeckling of Medical Ultrasound Images
Abstract— This paper presents a review of wavelet thresholding techniques for despeckling of medical ultrasound images. An ultrasound image is first transformed into wavelet domain and then the wavelet coefficients are processed by different wavelet thresholding techniques. The denoised image is obtained by taking the inverse wavelet transform of the modified wavelet coefficients. The performan...
