Field Documentation

guint NvDsPreProcessUnit::batch_index = 0

Index of the frame in the batched input GstBuffer.

Not required for classifiers.

Definition at line 232 of file nvdspreprocess_interface.h.

gpointer NvDsPreProcessUnit::converted_frame_ptr = nullptr

Pointer to the converted frame memory.

This memory contains the frame converted to RGB/RGBA and scaled to network resolution. This memory is given to Output loop as input for mean subtraction and normalization and Tensor Buffer formation for inferencing.

NvDsFrameMeta* NvDsPreProcessUnit::frame_meta = nullptr

Definition at line 229 of file nvdspreprocess_interface.h.

gulong NvDsPreProcessUnit::frame_num = 0

Frame number of the frame from the source.

Definition at line 234 of file nvdspreprocess_interface.h.

NvBufSurfaceParams* NvDsPreProcessUnit::input_surf_params = nullptr

The buffer structure the object / frame was converted from.

Definition at line 236 of file nvdspreprocess_interface.h.

NvDsObjectMeta* NvDsPreProcessUnit::obj_meta = nullptr

NvDsObjectParams belonging to the object to be classified.
