High-throughput characterisation of bull semen motility using differential dynamic microscopy
Fig 1
Example of tracking a spermatozoon head motion based on a movie recorded at 10× magnification at 100fps for 0.5 s.
VSL (red), VAP (blue and green), VCL (black), ALH and BCF calculated for this track are stated (see text for the definitions). Coloured lines indicate the distance used in calculating the corresponding speed (see section on Tracking analysis for explanation of VAP). Inset: The oscillatory component of displacement ros plotted against time.
