SegmentImage_Edges


Module: FoundationPro

Segments an image into blobs using image edges as their borders.

Applications

Detection of objects of undefined shape, but characterized by good contrast to the background and fairly uniform internal brightness.
Name Type Range Description
Input value inImage Image Image from which blobs are extracted
Input value inRoi Region* Range of pixels to be processed
Input value inFrameSize Integer 0 - How many pixels from the region border are excluded from the results
Input value inStdDev Real 0.0 - Amount of smoothing used by the edge filter
Input value inEdgeThreshold Real 0.0 - Sufficient edge strength; edges of that strength will always be detected
Input value inEdgeHysteresis Real 0.0 - Value by which the edge threshold is decreased for edge points neighboring with sufficiently strong edges
Input value inMaxJoiningDistance Real 0.0 - Maximal distance between edges that can be joined
Input value inMinArea Integer 0 - Minimal area of a detected blob
Input value inMaxArea Integer* 0 - Maximal area of a detected blob
Input value inComputeNestingLevels Bool Flag indicating whether nesting levels should be computed
Input value inEdgeClosing Integer 0 - Radius of enclosing small holes in the detected blobs
Output value outBlobs RegionArray Blobs extracted from the input image
Output value outNestingLevels IntegerArray Nesting level of each extracted blob
Diagnostic input diagEdgeRegion Region Region of the found edges

Examples

SegmentImage_Edges performed on an image of labels; default parameters.
