Postprocessing of images obtained from shear beam imaging

In this paper it is shown that several image processing techniques can be employed to reduce the noise and improve the overall quality of images obtained from Shear-Beam- Imaging. Presented are several standard techniques used in the suppression of signal dependent noise, speckle in this case. While these techniques are shown to be adequate when speckle is the predominant noise source, they become less effective as the signal independent, or detector, noise increases. To this end we also propose a technique to effectively deal with both the signal dependent and signal independent noise in these images.
