Sperm Motility

This analysis tracks sperms and classifies them by speed.

Options

Analysis Name

Name of your analysis.

Threshold

The threshold bar enables selecting low and high intensity thresholds. Only the pixels within this interval will be taken to make objects visualized as a binary mask.

More information about thresholding can be found here: Thresholding.

Smooth / Clean / Fill holes / Separate

These tools function as filters. Use them to improve your image quality before processing. Use Smooth (to smooth rough edges) / Clean (removes small objects) / Fill Holes / Separate to get the objects.

Size (px)

Position the sliders to restrict the area of the sizes of the detected sperms.

Circularity

Position the sliders to restrict sperms in your image with desired circularity.

Elongation

Please see Elongation.

Max Object Speed

Select if a speed limit is required. Only trajectories of sperms moving within the speed limit will be considered. Use this option when you are sure the sperm cannot move faster than the set limit.

StDev Multiplication Factor

Please see Standard Deviation Multiplication Factor (Tracking Options).

Join tracks up to n frames apart

Tracks which are not directly connected in time can be joined together after specifying the frame gap.

VAP Averaging

Specifies the average path velocity parameter.

Remove track shorter than n segments

Tracks shorter than a specified number of segments can be removed from the analysis.
