- Abstract: Fish tracking plays a vital role in understanding fish behavior and ecology.
However, existing tracking methods face challenges in accuracy and robustness
dues to morphological change of fish, occlusion and complex environment. This
paper proposes FishMOT(Multiple Object Tracking for Fish), a novel fish
tracking approach combining object detection and IoU matching, including basic
module, interaction module and refind module. Wherein, a basic module performs
target association based on IoU of detection boxes between successive frames to
deal with morphological change of fish; an interaction module combines IoU of
detection boxes and IoU of fish entity to handle occlusions; a refind module
use spatio-temporal information uses spatio-temporal information to overcome
the tracking failure resulting from the missed detection by the detector under
complex environment. FishMOT reduces the computational complexity and memory
consumption since it does not require complex feature extraction or identity
assignment per fish, and does not need Kalman filter to predict the detection
boxes of successive frame. Experimental results demonstrate FishMOT outperforms
state-of-the-art multi-object trackers and specialized fish tracking tools in
terms of MOTA, accuracy, computation time, memory consumption, etc..
Furthermore, the method exhibits excellent robustness and generalizability for
varying environments and fish numbers. The simplified workflow and strong
performance make FishMOT as a highly effective fish tracking approach. The
