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_GPU_POSTPROCESS 

Async GPU post-processing is run after inference.

DW_LSP_DETECTOR_STAGE_CPU_POSTPROCESS 

After inference CPU runs post processing.
