11. Datasheet (Optiflow)¶
FPS : Effective framerate at which the application runs
Total time : Average time taken to process each frame, which includes pre-processing, inference and post-processing time
Inference time : Average time taken to infer each frame
CPU loading : Loading on different CPU cores present
DDR BW : DDR read and write BW used
HWA Loading : Loading on different Hardware accelerators present
Following are the latest performance numbers of the OpTIFlow demos:
