| inIgnoreBoundaryObjects | bool | False | Flag indicating whether objects crossing image boundary should be ignored or not. Default value: False. | |
| inMaxDifference | float | <0.0f, INF> | 5.0f | Maximum accepted average difference between pixel values. Default value: 5.0f. |
| inMinDistance | float | <0.0f, INF> | 10.0f | Minimum distance between two matches. Default value: 10.0f. |
 | outObjects | System.Collections.Generic.List<Fil.Object2D> | Found objects. | ||
| outPyramidHeight | Ftl.Optional<int> | Highest pyramid level used to speed up computations. | ||
| outAlignedSearchRegion | Ftl.Optional<Fil.ShapeRegion> | Transformed input shape region. | ||
 | diagImagePyramid | Fil.Diagnostic<System.Collections.Generic.List<Fil.Image>> | Pyramid of iteratively downsampled input image. | ||
| diagMatchPyramid | Fil.Diagnostic<System.Collections.Generic.List<Fil.Image>> | Locations found on each pyramid level. | ||
| diagScores | Fil.Diagnostic<System.Collections.Generic.List<System.Collections.Generic.List<float>>> | Scores of found matches on each pyramid level. |
