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