Thus, ActiPHV improves the result compared to existing approaches. From our experiments it turned out that ActiPHV yields a higher accuracy compared to previous methods, which enhances the sensitivity and accuracy of the assay. We used manual tracking data and automatically determined tracking data.
Since manual tracking is very time-consuming and therefore not appropriate for the analysis of IVMA images in daily labwork, accurate automatic tracking methods are essential. Different methods for filament tracking in IVMA images have been introduced. In our work, we used Diatrack Vallotton and Olivier, ; Vallotton et al. This tracking method yields good results when detection parameters are adjusted manually for each image sequence.
Even though there are partly tracking errors data not shown , they hardly influence the result of ActiPHV for the maximum velocity, which shows that our method is robust. Thus, our method advances the analysis of IVMA images and enables to better exploit the power of the assay. KR supervised the development of the method, while L-MS and RF supported the work from the laboratory point of view by regular review and discussion of intermediate results. NB drafted the code article, which was critically revised by all authors.
