Description[edit | edit source]

This component detects the blobs resulting of a thresholding step and keeps those with their area, orientation and compactness between specified boundaries. It is really close to the blob detection component. The only difference is that the result is a black and white image and not particles. Therefore, additional binary processing can be done after this method (Such as erosion or dilation).

Input[edit | edit source]

SwisTrack BinaryImage.png

A binary (black and white) image.

Output[edit | edit source]

SwisTrack BinaryImage.png

A binary (black and white) image.
