A new approach to edge detection

This paper describes an approach to the edge detection based on directional image searching for edges. This is a new idea of detecting edges because the algorithm discussed generates only some selected points of one particular edge. Using for calculation only some of the points surrounding the desired edge results in high computation speed of this system. The presented algorithm has also some specific skills useful in medical imaging such as automatic crossing the artefacts. The article contains examples of how this system works on synthetic images as well as its application to semiautomatic edge detection in real CT and MR images.
