guint 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.

void* NvDsOpticalFlowMeta::data

Holds a pointer to the motion vector.

Definition at line 67 of file nvds_opticalflow_meta.h.

gulong NvDsOpticalFlowMeta::frame_num

Holds the current frame number of the source.

Definition at line 65 of file nvds_opticalflow_meta.h.
