SegmentImage_Edges

Advanced

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
