ImageProjection
Header: | AVL.h |
---|---|
Namespace: | avl |
Computes the average (or other statistic) for each image row or column and then merges the obtained results into a profile.
Syntax
void avl::ImageProjection ( const avl::Image& inImage, atl::Optional<const avl::Region&> inRoi, avl::ProjectionDirection::Type inProjectionDirection, avl::ProjectionMode::Type inProjectionMode, avl::Profile& outProfile )
Parameters
Name | Type | Default | Description | |
---|---|---|---|---|
inImage | const Image& | Monochromatic image | ||
inRoi | Optional<const Region&> | NIL | Range of pixels to be processed | |
inProjectionDirection | ProjectionDirection::Type | Combine pixel values for image rows (horizontal) or columns (vertical) | ||
inProjectionMode | ProjectionMode::Type | Sum | Determines how the pixel values are combined | |
outProfile | Profile& | Output profile |
Requirements
For input inImage only pixel formats are supported: 1⨯uint8, 1⨯int8, 1⨯uint16, 1⨯int16, 1⨯int32, 1⨯real.
Read more about pixel formats in Image documentation.
