A new algorithm for contrast enhancement and noise removal from the ultrasound images is proposed. At first, Sticks filteris used to remove the initial noise from the ultrasound images. Then the image brightness is improved. Finally multi-scale and new generation of curvelet transform, the coefficient adaptive correction of these transforms, non-linear modificationand adaptive functions suggested here are applied to enhance the final contrast and removing any noise from the kidney ultrasound images.
