DL_SegmentInstances

Header:	AVLDL.h
Namespace:	avl
Module:	DeepLearning

Executes a Segment Instances model on a single input image.

Syntax

void avl::DL_SegmentInstances
(
	const avl::Image& inImage,
	atl::Optional<const avl::Region&> inRoi,
	const avl::SegmentInstancesModelId& inModelId,
	const atl::Optional<float>& inMinDetectionScore,
	const atl::Optional<int>& inMaxObjectsCount,
	atl::Array<avl::Box>& outBoundingBoxes,
	atl::Array<int>& outClassIds,
	atl::Array<atl::String>& outClassNames,
	atl::Array<float>& outScores,
	atl::Array<avl::Region>& outMasks
)

Parameters

Name	Type	Range	Default	Description
inImage	const Image&			Input image
inRoi	Optional<const Region&>		NIL	Limits the area where objects may be located
inModelId	const SegmentInstancesModelId&			Segment Instances model stored in a specific disk directory
inMinDetectionScore	const Optional<float>&	0.0 - 1.0	NIL	Sets a minimum required score for an object to be returned. If not set, a value determined during the training is used
inMaxObjectsCount	const Optional<int>&	1 -	NIL	Limits maximum number of returned objects. If not set, a value determined during the training is used
outBoundingBoxes	Array<Box>&			Returns bounding boxes of the found objects
outClassIds	Array<int>&			Returns ids of the found object classes
outClassNames	Array<String>&			Returns names of the found objects classes
outScores	Array<float>&			Returns scores of the found objects
outMasks	Array<Region>&			Returns masks of the found objects

Requirements

For input inImage only pixel formats are supported: 1⨯uint8, 3⨯uint8.

Read more about pixel formats in Image documentation.

Hints

It is recommended that the deep learning model is deployed with DL_SegmentInstances_Deploy first and connected through the inModelId input.
If one decides not to use DL_SegmentInstances_Deploy, then the model will be loaded in the first iteration. It will take up to several seconds.

Remarks

This filter should not be executed along with running Deep Learning Service as it may result in degraded performance or even out-of-memory errors.
