Ripplet domain non-linear filtering for speckle reduction in ultrasound medical images
The paper presents a new method for speckle reduction in ultrasound medical images. The proposed method combines the bilateral filter and ripplet thresholding to remove the speckles in ultrasound images. The proposed method provides better performance for despeckling of ultrasound images compared to several existing methods.
