Abstract:

Speckle noise is a different kind of noise which mostly occurs in coherence imaging system like ultrasound images, lasers, sonar, synthetic aperture of radar etc. So, in ultrasound images, the presence of speckle noise results in decrement of quality of an image and due this noise it becomes difficult for human and doctors to diagnose. So it cannot be possible to interpret the change with naked eyes. It also becomes hard to differentiate between speckle noise and clinical information because speckle noise behaves like information. So it is necessary to overcome this problem by reducing noise. Many numerical methods are proposed for filtering of speckle noise or speckle suppression. This paper presents a comparative review of various speckle reduction filters. These filters have different results and behaviour. Similarly some filters do better coherence, edge enhancement and segmentation etc. In the end, it provides some commonly used filtering techniques for de-noising.
