Smoothing of ultrasound images using a new selective average filter
作者：
Highlights：
• A new method is proposed to perform selective smoothing of images affected by speckle noise.
• A new smoothing criterion is defined for the average smoothing filter.
• The convolution window of the smoothing filter is adjustable.
• The method is evaluated using real ultrasound medical images based on image quality metrics.
• The proposed method produced better results than the current methods evaluated.
