摘要

The method involves determining a brightness region between upper pixel values and lower pixel values representing objects e.g. vascular tree of a patient (4), in histogram of an x-ray image (2). A planar image is produced from the x-ray image, where pixels with pixel values in the brightness area are set to a value in the planar image. The planar image is straightened by an edge filter, where pixel in a transition area is assumed to be larger than an intermediate value. An outline is formed from the planar image as the quantity of image pixels formed with the intermediate value.
