dwLightSourceDetectorStage

enum dwLightSourceDetectorStage

Enumerator
DW_LSP_DETECTOR_STAGE_GPU_PREPROCESS	Input image is preprocessed on GPU side with certain predefined transformations in order to have the right properties required by DNN inference.
DW_LSP_DETECTOR_STAGE_GPU_INFERENCE	DNN inference is run on prepared image.
DW_LSP_DETECTOR_STAGE_CPU_POSTPROCESS	After inference CPU runs post processing.

Function Documentation

dwLightSourceDetector_bindInput()

DW_API_PUBLIC dwStatus dwLightSourceDetector_bindInput	(	const dwImageCUDA *	imageRGB,
		const dwImageCUDA *	imageBayer,
		dwLightSourceDetectorHandle_t	obj
	)

Binds the input images to the detector.

Parameters

[in]	imageRGB	Pointer to RGB image where the detector is to be applied.
[in]	imageBayer	Pointer to Bayer image where we apply linear HDR threshold.
[in]	obj	Specifies the LspDetector handle.

Returns

DW_SUCCESS, DW_INVALID_HANDLE, DW_BAD_CAST, DW_INVALID_ARGUMENT

dwLightSourceDetector_bindOutput()

DW_API_PUBLIC dwStatus dwLightSourceDetector_bindOutput	(	dwLightSourceDetectorOutput *	output,
		dwLightSourceDetectorHandle_t	obj
	)

Bind the ouput of the detector to object.

Parameters

[in,out]	output	Pointer to an object output structure.
[in]	obj	Specifies the LightSourceDetector handle.

Returns

DW_SUCCESS, DW_INVALID_HANDLE, DW_BAD_CAST, DW_INVALID_ARGUMENT

dwLightSourceDetector_process()

DW_API_PUBLIC dwStatus dwLightSourceDetector_process	(	dwLightSourceDetectorStage	stage,
		dwLightSourceDetectorHandle_t	obj
	)

Perform object detection stages.

Inputs and outputs must be bound before this call.

Parameters

[in]	stage	Processing stage to run.
[in]	obj	Specifies the LightSourceDetector handle.

Returns

DW_SUCCESS operation completed successfully DW_INVALID_ARGUMENT one of the parameters are invalid (nullptr or null handle)
