Zebrafish larvae exploration and aversive chemotaxis dataset

This dataset contains recordings of larval zebrafish behavior. The full details are described in the paper \"A lexical approach for identifying behavioral action sequences\". 

The experiment investigates zebrafish larvae behavior in free swimming and aversive chemotaxis conditions. In each experiment, 12 larvae (7 dpf) are placed in 12 rectangular wells. Ten min-long videos were recorded at 160 Hz with an exposure time of 1 ms, and a pixel size of 70 µm using a ViewWorks camera (Basler acA2040-180km) controlled by the Hiris software (R&D Vision, Nogent sur Marne, http://www.rd-vision.com/r-d-vision-eng).

The fish are tracked using a custom-made software, Zebrazoom (https://zebrazoom.org/). The algorithm begins by locating all the wells and by extracting the background of the video. ZebraZoom first applies a series of actions to detect the animal in each well: i) contours of head and entire body are detected using active contours, ii) the center of the head is identified as the c...
