Steger, C. (1998). An unbiased detector of curvilinear structures. IEEE Transactions on Pattern Analysis and Machine Intelligence, 20(2), 113–125. doi:10.1109/34.659930
The paper describes a method to extract lines and their widths. The method proposed has some characteristics, that make it extremely useful for the detection of filament like structures in biological images.
- The correct centre-line is found even when the line-profiles are asymmetric
- The width of the filament is detected
- Crossing filaments do not disturb the detection since the environment is taken into consideration
- The parameters are meaningful: max. line width, min. contrast, ...
- Yields results with sub-pixel resolution
An ImageJ-plugin named Ridge Detection implementing the method has been written by Thorsten Wagner and Mark Hiner.
