EnhanceMultipleObjectMatches

Advanced

Module: MatchingPro

Improves accuracy of multiple object matching by adding a subpixel-precise adjustment.

Applications

Usually used after an edge-based template matching tool.
Name Type Description
inImage Image Input image
inObjects Object2DArray Input objects
inObjectEdges PathArrayArray Input objects edges
inAllowScale Bool Determines if the object scale can be adjusted
outObjects Object2DArray Objects with enhanced accuracy
outObjectEdges PathArrayArray Edges of objects with enhanced accuracy

Hints

  • In order to use the filter to fine-tune the results of template matching, connect the outObjects and outObjectEdges outputs of the template matching filter to the inObjects and inObjectEdges inputs, and the same input image to the inImage input. By default, the outObjects and outObjectEdges outputs of the template matching filter are hidden, so one should use "Show/Hide Ports" option to make them visible.
  • When using template matching with EnhanceMultipleObjectMatches filter, you may try to speed up template matching by increasing its inMinPyramidLevel parameter. The potential loss of template matching precision should be mitigated by the EnhanceMultipleObjectMatches filter.

Hardware Acceleration
