ABSTRACT:
Image processing adapts to speckle. Speckle is identified from signal transitions. For example, peaks, valleys or mean crossings of image signals as a function of space or spatial location are identified. A speckle characteristic, such as speckle size, is estimated from the signal transitions. The estimation may be limited to soft tissue regions to reduce the effects of specular targets and noise on speckle estimation. The speckle is estimated for local regions or an entire image. By estimating speckle for local regions, image processing may account adaptively for regional variation in speckle size.
