Field Documentation

guint NvDsOpticalFlowMeta::cols

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

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

Definition at line 63 of file nvds_opticalflow_meta.h.

void* NvDsOpticalFlowMeta::data

motion vector data pointer

Definition at line 69 of file nvds_opticalflow_meta.h.

gulong NvDsOpticalFlowMeta::frame_num

current frame number of the source

Definition at line 67 of file nvds_opticalflow_meta.h.

guint NvDsOpticalFlowMeta::mv_size
