Opencv vs NCSDK performance

Hello i did some test on inference with the same model in openCv and with native SDK, and surprisingly I get a better result with openCv than with the SDK, and I'm talking about a big difference.

Im on a rpi 3b, raspbian stretch, openVino last version and 2019 R3 model

Is that the expected behavior??

Best Regards

Hi Ignacio, 

Which model did you use to compare results? Are you able to include your outputs? I would like to verify this on my end if possible. 

Are you using the Neural Compute Stick 2 on the RPI? 

 

 

 

Just to clarify: the NCSDK (mentioned in the subject line) is now unsupported. 

Best Regards,

Sahira

Hello

First i have to say sorry as i double posted this and that not my intention, i first send the question and as i do not see published i sent it again.....

Here is the original version, you can find code and model linked on last post
https://software.intel.com/en-us/forums/intel-distribution-of-openvino-toolkit/topic/856367

The model is the one that i downloaded from here
https://download.01.org/opencv/2019/open_model_zoo/R3/20190905_163000_models_bin/

Yes im using Neural Compute Stick 2 on the rpi, and yes sorry i meant openvino inference engine not ncsdk

I did not do anything extrange on my code, only follow code samples and i was surprised to find that openCv is faster than openvino inference_engine.

I even tried asyn version on both approach and still openCv is faster

Maybe im doing something wrong, thats why im asking if this is the expected behaviour


Best Regards
