METHOD FOR EXTRACTING BLOOD VESSEL OF HOLLOW ORGAN, EXTRACTION PROCESSING PROGRAM OF BLOOD VESSEL OF HOLLOW ORGAN, AND IMAGE PROCESSOR

摘要

PPROBLEM TO BE SOLVED: To provide a method for extracting the blood vessel of a hollow organ, an extraction processing program of the blood vessel of the hollow organ, and an image processor by which a measuring object is quantitatively measured with respect to the hollow organ such as an eye ball, and the robust extraction of the blood vessel is automated. PSOLUTION: A quality measurement area of each frame for extracting a blood vessel area is given to the stereoscopic model (coordinate information) of the hollow organ prepared in advance. According to the judging reference of each pixel, an area belonging to a blood vessel area is judged based on the pixel value of the quality measurement area of a first frame, and the judging reference in a second frame connected with the first frame is set based on the pixel value of an area obtained by including the judged area in the blood vessel area. As one of the judging references, a density center value in a local area is utilized. PCOPYRIGHT: (C)2004,JPO&NCIPI
