RemapImage
Applies a precomputed image transform, defined by a spatial map object.
| Name | Type | Description | |
|---|---|---|---|
 |
inImage | Image | Input image |
|
inSpatialMap | SpatialMap | Definition of the transformation |
|
inMapRoi | Region* | Defines which elements of the spatial map are valid |
 |
outImage | Image | Output image |
Applications
Fast (precomputed) image transformations, especially for view undistortion or object geometry correction (e.g. pos recognition of labels on cylindrical bottles).
Description
The operation applies an arbitrary spatial transformation to an image using a SpatialMap object. The input image has to be compatible with the given map. You can check if a map is compatible with an image using TestSpatialMapApplicability.
Hints
- Connect the inImage input with an appropriate image source.
- Connect the inSpatialMap input with a spatial map. This can be for example the result of the CreatePerspectiveMap_Points filter or similar.
