Field Documentation

◆ cols

unsigned int NvDsOpticalFlowMeta::cols

Holds the number of columns in the frame for given block size, e.g.

if block size is 4 and frame width is 1280, then the number of columns is (1280/4) = 320.

Definition at line 60 of file nvds_opticalflow_meta.h.

◆ cost

void* NvDsOpticalFlowMeta::cost

Holds a pointer to the cost of the motion vector.

Definition at line 70 of file nvds_opticalflow_meta.h.

◆ cost_size

unsigned int NvDsOpticalFlowMeta::cost_size

Holds the size of the confidence values of the motion vector.

Definition at line 64 of file nvds_opticalflow_meta.h.

◆ data

void* NvDsOpticalFlowMeta::data

Holds a pointer to the motion vector.

Definition at line 68 of file nvds_opticalflow_meta.h.

◆ frame_num

unsigned long NvDsOpticalFlowMeta::frame_num

Holds the current frame number of the source.

Definition at line 66 of file nvds_opticalflow_meta.h.

◆ mv_size

unsigned int NvDsOpticalFlowMeta::mv_size

Holds the size of the motion vector.

◆ rows

unsigned int NvDsOpticalFlowMeta::rows

Holds the number of rows in the frame for a given block size, e.g.

if block size is 4 and frame height is 720, then the number of rows is (720/4) = 180.
