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 59 of file nvds_opticalflow_meta.h.

data

void* NvDsOpticalFlowMeta::data

Holds a pointer to the motion vector.

Definition at line 65 of file nvds_opticalflow_meta.h.

frame_num

unsigned long NvDsOpticalFlowMeta::frame_num

Holds the current frame number of the source.

Definition at line 63 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.
