Description[edit]

This component detects the blobs resulting of a thresholding step and keeps those with their area, orientation and compactness between specified bondaries. A maximum number of object can be selected, and in this case, only the biggest objects will be kept.

Input[edit]

A binary (black and white) image.

Output[edit]

SwisTrack Particles.png

Particles.
