DeepLearning_ClassifyObject


Performs whole image classification using a trained deep-learning model.

Header:AVL.h

Syntax

C++
C#
 
void avl::DeepLearning_ClassifyObject
(
	DeepLearningConnectionState& ioState,
	const avl::Image& inImage,
	const atl::Optional<avl::Region>& inRoi,
	const avl::DeepModel_Classification& inDeepModel,
	atl::Array<avl::ClassConfidence>& outConfidences,
	atl::String& outClassName,
	int& outClassIndex,
	float& outScore,
	avl::Image& diagRelevanceHeatmap
)

Parameters

Name Type Default Description
ioState DeepLearningConnectionState& Object used to maintain state of the function.
inImage const Image& Input image
inRoi const Optional<Region>& NIL Area of interest
inDeepModel const DeepModel_Classification& Trained model
outConfidences Array<ClassConfidence>& Returns confidences for all classes
outClassName String& Returns name of the class with highest confidence
outClassIndex int& Returns the index of the class with highest confidence
outScore float& Returns the value of the highest confidence
diagRelevanceHeatmap Image& Returns heatmap indicating how strong specific parts of image influenced classification result

Requirements

For input inImage only pixel formats are supported: 1xuint8, 3xuint8.

Read more about pixel formats in Image documentation.

Hints

Loading Deep Learning Model may take longer timer. Consider using DeepLearning_LoadModel for pre-loading model before execution starts.

Remarks

  • Model provided on inDeepModel input will be loaded to service automatically on first usage of Deep Learning filters.
  • Service automatically releases and loads model into its memory. It may result in releasing model previously loaded using DeepLearning_LoadModel filter.
  • These filters only communicates with service and cannot be use for parallel computation.

Errors

Error type Description
DomainError Empty ROI region in DeepLearning_ClassifyObject
DomainError Size of ROI differs from size of image in DeepLearning_ClassifyObject
DomainError Invalid DeepModel in DeepLearning_ClassifyObject.
DomainError Empty image in DeepLearning_ClassifyObject.
IoError Missing confidences.
IoError Received invalid number of heatmaps.
