LocateMultipleObjects_Edges_Deprecated

Basic

Module: MatchingPro

Finds all occurrences of a predefined template on an image by comparing object edges.

Applications

Detection of multiple objects whose outlines are sharp and rigid. Often one of the first filters in a program.
Name Type Range Description
Input value inImage Image Image on which object occurrences will be searched
Input value inSearchRegion Region* Region of possible object centers
Input value inEdgeModel EdgeModel Model of objects to be searched
Input value inMinPyramidLevel Integer 0 - 12 Defines the lowest pyramid level at which object position is still refined
Input value inMaxPyramidLevel Integer* 0 - 12 Defines the total number of reduced resolution levels that can be used to speed up computations
Input value inEdgeThreshold Real 0.01 - Minimum strength of edges used for matching with the model
Input value inEdgePolarityMode EdgePolarityMode Defines how edges with reversed polarity will contribute to the object score
Input value inEdgeNoiseLevel EdgeNoiseLevel Defines how much noise the objects edges have
Input value inIgnoreBoundaryObjects Bool Flag indicating whether objects crossing image boundary should be ignored or not
Input value inMinScore Real 0.0 - 1.0 Minimum score of object candidates accepted at each pyramid level
Input value inMinDistance Real 0.0 - Minimum distance between two found objects
Output value outObjects Object2DArray Found objects
Output value outObjectEdges PathArrayArray Model edges of the found objects
Output value outPyramidHeight Integer Highest pyramid level used to speed up computations
Diagnostic input diagEdgePyramid ImageArray Image edges used for matching at each pyramid level
Diagnostic input diagMatchPyramid ImageArray Candidate object locations found at each pyramid level
Diagnostic input diagScores RealArrayArray Scores of the found objects at each pyramid level

Hardware Acceleration
