DeepLearning_ClassifyObject
Header: | AVLDL.h |
---|---|
Namespace: | avl |
Performs whole image classification using a trained deep-learning model.
Syntax
void avl::DeepLearning_ClassifyObject ( const avl::Image& inImage, atl::Optional<const avl::Rectangle2D&> inRoi, atl::Optional<const avl::CoordinateSystem2D&> inRoiAlignment, const avl::DeepModel_Classification& inDeepModel, const bool inCreateRelevanceHeatmap, atl::Array<avl::ClassConfidence>& outConfidences, atl::String& outClassName, int& outClassIndex, float& outScore, avl::Image& outRelevanceHeatmap )
Parameters
Name | Type | Default | Description | |
---|---|---|---|---|
inImage | const Image& | Input image | ||
inRoi | Optional<const Rectangle2D&> | NIL | Area of interest | |
inRoiAlignment | Optional<const CoordinateSystem2D&> | NIL | ||
inDeepModel | const DeepModel_Classification& | Trained model | ||
inCreateRelevanceHeatmap | const bool | False | Enable-Disable create relevance heatmap | |
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 | ||
outRelevanceHeatmap | Image& | Returns heatmap indicating how strong specific parts of image influenced classification result |
Requirements
For input inImage only pixel formats are supported: 1⨯uint8, 3⨯uint8.
Read more about pixel formats in Image documentation.
Hints
Loading Deep Learning Model may take longer timer. Consider using DeepLearning_LoadModel_ObjectClassification for pre-loading model before execution starts.
Remarks
- Model provided on inDeepModel input will be loaded automatically on first usage of this filter.
- 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. However, if stopping Deep Learning Service is not an option (e.g. program uses other Deep Learning filters related to Anomaly Detection or Instances Segmentation) it is advised that this filter should be executed before other Deep Learning filters. Such "warm up" execution does not have to use real image or roi as long as provided image and roi have similar size.
Multithreaded environment
This function is not guaranteed to be thread-safe. When used in multithreaded environment, it has to be manually synchronized.
Errors
