Summary

[edit]
Description
English: Video illustrating how the movement of the ants is analysed and correlated to the pheromone maps. Every twenty frames (0.4 s) each ant present under the field of view of the camcorder is detected and its position marked. The ant is followed over two intervals of 10 frames each and its path is described by two paths of ten frames each and a turning angle . These measures of ant movement are stored together with the whole pheromone map around the ant position in correspondence with the turning angle (more precisely with the map computed 16 seconds before the tracking event). This analysis is repeated every twenty frames for the whole duration of the arena level videos. Only the tracking events for which the ant was clearly detected in all the frames and did not meet any other ant were kept for the analyses.
