◆ NvDsPostProcessNetworkType

enum NvDsPostProcessNetworkType

Defines network types.

Enumerator
NvDsPostProcessNetworkType_Detector	Specifies a detector. Detectors find objects and their coordinates, and their classes in an input frame.
NvDsPostProcessNetworkType_Classifier	Specifies a classifier. Classifiers classify an entire frame into one of several classes.
NvDsPostProcessNetworkType_Segmentation	Specifies a segmentation network. A segmentation network classifies each pixel into one of several classes.
NvDsPostProcessNetworkType_InstanceSegmentation	Specifies a instance segmentation network. A instance segmentation network detects objects, bounding box and mask for objects, and their classes in an input frame
NvDsPostProcessNetworkType_Other	Specifies other. Output layers of an "other" network are not parsed by NvDsPostProcessContext. This is useful for networks that produce custom output. Output can be parsed by the NvDsPostProcessContext client or can be combined with the Gst-nvinfer feature to flow output tensors as metadata.
