Abstract:
1. A radiographic image processing apparatus for processing a radiographic image having undergone radiography, comprising: a low-frequency image generating device for generating a low-frequency image having a lower frequency than the radiographic image through decreasing a spatial resolution of the radiographic image; a characteristic extracting device for performing characteristic extraction through determining characteristic amounts in accordance with signal level differences between any pixel of the low-frequency image and peripheral pixels thereof and generating a characteristic image by bringing the characteristic amounts into correspondence with each pixel of the low-frequency image; a low-frequency characteristic generating device for generating a low-frequency characteristic as an image having a lower frequency than the characteristic image through decreasing a spatial resolution of the characteristic image; and an area extracting device for selecting a characteristic as an edge of a radiation area based on the low-frequency characteristic, and extracting the radiation area from the radiographic image.
