EnhanceSingleObjectMatch

Advanced

Module: MatchingPro

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

Applications

Usually used after an edge-based template matching tool.
Name Type Description
Input value inImage Image Input image
Input value inObject Object2D Input object
Input value inObjectEdges PathArray Input object edges
Input value inAllowScale Bool Determines if the object scale can be adjusted
Output value outObject Object2D Object with enhanced accuracy
Output value outObjectEdges PathArray Edges of the object with enhanced accuracy

Hints

  • In order to use the filter to fine-tune the results of template matching, connect the outObject and outObjectEdges outputs of the template matching filter to the inObject and inObjectEdges inputs, and the same input image to the inImage input. By default, the outObject and outObjectEdges outputs of the template matching filter are hidden, so one should use "Show/Hide Ports" option to make them visible.

Examples

When using template matching with EnhanceSingleObjectMatch 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 EnhanceSingleObjectMatch filter, as shown in the images below:
