Automated construction of three dimensional image processing procedures by pictorial example with application to medical images

Presents an expert system for three dimensional image processing. In analyzing three dimensional gray images, e.g. CT images, a process for extraction of interest regions from each image is frequently required. However, it is difficult to construct all extinction procedure with parameters optimized for each purpose. The proposed system can automatically construct a three dimensional object extraction procedure based on a sample figure presented by a user. The authors applied this system to generating a cancer extraction procedure from a chest CT image and confirmed that the constructed procedure can extract nearly the same region as the real cancer shadow from the image.
