IMAGE ANALYSIS SYSTEM AND METHOD

摘要

A method comprising the steps of: receiving image data representing an image; processing the data to generate ori-entation information; processing the data using the orientation information to measure a quantity called local phase in a direction perpendicular to the orientation of a putative vessel; using the phase measurements from three collinear image locations or from two locations to detect the centreline of a symmetric image structure, such as a blood vessel, and to locate a centrepoint defined by the intersection of the centreline with the line created by the measurement locations.
