why this code is not working?
what i'm missing?
Can anyone please help with this issue.

Hello, we do not offer technical support for the secondary development of the software. For more details, you can refer to https://github.com/airockchip/librga. The example routines provided by Rockchip include the standard usage of imcvtcolor.

Is the luckfox pico sdk, opencv library supports face detection?

The luckfox pico will consume excessive memory resources when opening OpenCV and the performance is not good. Generally, the lightweight and optimized OpenCV-Mobile is used. There is an introduction on how to implement face detection using OpenCV-Mobile + RKNN on the wiki.

I'm using the Opencv which is in rkmpi example of rtsp retinaface. The avg use of CPU is 60-70% and RAM around 23%(MAX).
I have removed the rtsp as i'm using on board display.

Is this much CPU and RAM use normal?

Running "luckfox_pico_rtsp_retinaface" results in CPU usage around 60-70% and RAM usage around 20-30%, which are all within normal ranges.

Ok
thank you
