VIM3 duration time for benchmark vs. recognize

[Søren Hyltoft]

Hi

Would you please explain the duration time for the benchmark vs. recognize?
We use VIM3 with npu = true.
From the benchmark we achieve approximately 100ms per frame.
From recognize we achieve 286ms per frame?
Benchmark:

Recognize:

Hi,

Read https://www.doubango.org/SDKs/anpr/docs/Frequently_Asked_Questions_(FAQ).html#why-the-recognizer-application-is-slow

You can write your own benchmark as explained on the link

Most importantly, it’s useless to enable NPU if you’re disabling parallel processing
