Abstract:
By applying a hexagon-diamond search (HDS) method to an ultrasound image, the path of an object is able to be
monitored by extracting images into macro-blocks, thereby achieving image redundancy is reduced from one frame to
another, and also ascertaining the motion vector within the parameters searched. The HDS algorithm uses six search
points to form the six sides of the hexagon pattern, a centre point, and a further four search points to create diamond pattern within the hexagon that clarifies the focus of the subject area.
