Procedure for detection of contours of highly absorbent matter within an X-ray image involves image processing to determine potential contour closed paths and contrast determination of the correct path to improve image processing
Procedure for detection of contours of highly absorbent matter within an X-ray image involves image processing to determine potential contour closed paths and contrast determination of the correct path to improve image processing
Procedure involves determination of a number of closed paths in an X-ray image or an image derived from an X-ray image and then selection of one path from the number of closed paths as a contour dependent on the contrast on either side of the closed path. The closed paths are determined by determination of contour point candidates, using a high pass filter or gradient image, from the spatial path of the pixels of the X-ray image and determination of a number of line candidates which are comprised of a series of contour points and formation of a closed path from line segments (maximum four).
