A compounding method for reducing speckle noise applied in an ultrasound imaging apparatus is disclosed. The compounding method includes the steps of providing an object, measuring the object for obtaining a reference image by the ultrasound imaging apparatus, applying an external force to the object to deform the object, measuring the deformed object for obtaining an deformed object image at the same position, estimating an in-plane displacement field of the deformed object image for correcting an in-plane motion of the object to obtain a corrected image, and compounding the reference image with the corrected image to obtain a compounded image of the object for achieving the speckle noise reduction.
