AB The fruit fly Drosophila Melanogaster has become a model organism in the studyof neurobiology and behavior patterns. The analysis of the way the fly moves and itsbehavior is of great scientific interest for research on aspects such as drug tolerance,aggression or ageing in humans. In this article, a procedure for detecting, identifying andtracking numerous specimens of Drosophila by means of computer vision-based sensingsystems is presented. This procedure allows dynamic information about each specimen to becollected at each moment, and then for its behavior to be quantitatively characterized. Theproposed algorithm operates in three main steps: a pre-processing step, a detection andsegmentation step, and tracking shape. The pre-processing and segmentation steps allowsome limits of the image acquisition system and some visual artifacts (such as shadows andreflections) to be dealt with. The improvements introduced in the tracking step allow theproblems corresponding to identity loss and swaps, caused by the interaction betweenindividual flies, to be solved efficiently. Thus, a robust method that compares favorably toother existing methods is obtained.
