Abstract :
Ubiquitous echo is a portable ultrasound imaging equipment. We discuss an image sharpening method based on geometrical information by mathematical morphology with double structuring element (DSE) for on-line processing on ubiquitous echo. The sharpening method improves the contrast of tissue boundaries without speckle emphasis. The computational complexity of the morphological operations is reduced by chain rule of the operations and decomposition of the DSE not to delay refreshing the ultrasound moving image
