CPU consumption with Raspberry Pi

Hello,  
I'm currently using the human_pose_demo algorithm on my RPi 4, with the Intel Neural Stick 2, to detect person. Even with the stick, the program is consuming 80% (85% if I display the video) resources of the CPU. Is it normal?

Thanks in advance,
Siméon.

It could be video decoding and frame preprocessing. Are you using video file or camera for input?

I'm using camera (from the Pi interface, not USB).

Hi Siméon,


I am using a Pi 4 ( 4GB RAM and running Pi OS) with OpenVINO distribution 2021.1 and Logitech C925e USB camera. My CPU usage is approximate 48%.


Can you try running on a video file and compare to see if the Pi Camera is the cause of high CPU usage.


Regards,

Rizal
