Abstract

We present a method to separate insect flight trajectories in dynamic vision sensor data and for their mathematical description by smooth curves. The method consists of four steps: Pre-processing, clustering, post-processing, and curve fitting. As the time and space coordinates use different scales, we have rescaled the dimensions with data-based scale factors. For clustering, we have compared DBSCAN and MST-based clustering, and both suffered from undersegmentation. A suitable post-processing was introduced to fix this. Curve fitting was done with a non-parametric LOWESS smoother. The runtime of our method is sufficiently fast to be applied in real-time insect monitoring. The data used for evaluation only had two spatial dimensions, but the method can be applied to data with three spatial dimensions, too.
