segment

public ObjectCollection segment(Channel channel,
 Optional<ObjectMask> objectMask,
 Optional<ObjectCollection> seeds)
                         throws SegmentationFailedException

Description copied from class: SegmentChannelIntoObjects

Segments a channel to produce an object-collection.

Specified by:

segment in class SegmentChannelIntoObjects

Parameters:

channel - the channel to segment

objectMask - an object-mask that can restrict which areas of the channel are considered.

seeds - seeds that can be used to determine starting-points for segmentation regions.

Returns:

a newly created collection of objects for each segment. The created objects will always exist inside the channel's extent.

Throws:

SegmentationFailedException - if anything goes wrong during the segmentation.

isExitWithMinima

public boolean isExitWithMinima()

If true, exits early and just returns the minima, without any further segmentation

setExitWithMinima

public void setExitWithMinima(boolean exitWithMinima)

If true, exits early and just returns the minima, without any further segmentation
