Abstract
We propose a measurement method of Tail Beat Frequency (TBF) and Coast Phase (CP) of fish swimming for isolated fish in a school of fish with visual tracking. For analysis of fish swimming behaviors, features that represent fish movements, e.g., TBF and CP, have been commonly used in the fields of biological and fisheries researches. We propose a measurement method for such features using particle filter and apply the method to a large school of fish in an aquarium. Experimental results show that the TBFs and the CPs are measured with our method accurately enough for further analysis of fish behaviors. The average errors of the TBFs was 0.126 (Hz) and the precision and recall of the classification for CP detection were 0.945 and 0.879 respectively.
