Analysis of the inclination of elongated biological objects: microtubules
Robert Koprowski, Zygmunt Wróbel · Machine Graphics & Vision International Journal archive · 2008
In the paper we propose a new method for determining the inclination angle of microtubules. The method allows us to obtaining an angular inclination histogram, taking into account the area of microtubules rather than their number only. We present two kinds of microtubule approximation: global and local one. In the global approach microtubules are approximated with one or more straight lines, whereas the local approach defines a direction field for each pixel.
