Compares image edges with the edges of a perfect template. Significant differences are considered defects.
Name | Type | Range | Description | |
---|---|---|---|---|
inImage | Image | Input image | ||
inGoldenImage | Image | Reference image containing no defects | ||
inRoi | Region* | Range of pixels to be processed | ||
inStaticModel | Bool | Flag indicating whether the model should be created only in the first iteration | ||
inStdDevX | Real | 0.0 - | Amount of horizontal smoothing used by the edge filter | |
inStdDevY | Real* | 0.0 - | Amount of vertical smoothing used by the edge filter (Auto = inStdDevX) | |
inEdgeThreshold | Real | 0.0 - | Sufficient edge strength; edges of that strength will always be detected | |
inEdgeHysteresis | Real | 0.0 - | Value by which the edge threshold is decreased for edge points neighboring with sufficiently strong edges | |
inMaxDistance | Integer | 0 - | Maximal allowed distance between corresponding edges on the input and golden image | |
outDefects | Region | Region of detected defects | ||
outDefectsPresent | Bool | Flag indicating whether any defects were detected | ||
outMissingEdges | Region | Edges present on the golden image that are missing on the input image | ||
outExcessiveEdges | Region | Edges that are not present on the golden image | ||
outImageEdges | Region | Edges on the input image | ||
outGoldenEdges | Region | Edges on the golden image | ||
outMatchingEdges | Region | Golden edges present on the input image |
