Quantitative analysis of the dynamic behavior about membrane-bound secretory vesicles has proven to be important in biological research.
This paper proposes a novel approach to automatically identify the elusive fusion events between VAMP2-pHluorin labeled GLUT4 storage vesicles (GSVs) and the plasma membrane.
The differentiation is implemented to detect the initiation of fusion events by modified forward subtraction of consecutive frames in the TIRFM image sequence.
Spatially connected pixels in difference images brighter than a specified adaptive threshold are grouped into a distinct fusion spot.
The vesicles are located at the intensity-weighted centroid of their fusion spots.
To reveal the true in vivo nature of a fusion event, 2D Gaussian fitting for the fusion spot is used to derive the intensity-weighted centroid and the spot size during the fusion process.
The fusion event and its termination can be determined according to the change of spot size.
The method is evaluated on real experiment data with ground truth annotated by expert cell biologists.
The evaluation results show that it can achieve relatively high accuracy comparing favorably to the manual analysis, yet at a small fraction of time.
