Speeding up Extracting image features

[Antorhythms]

Hi Timo,
We have been using the Annotation-Tool to create new datasets for training.
The frame extraction takes though particularly long and only uses CPU.
We were wondering first of all if no GPU usage is normal here and if so how could we speed up the Extraction of image features for kmeans which currently takes more than 6-8 hours per video with videos of around 30min lenght.
Thanks a bunch for your help!

Hi Anto,

Extracting image features using k-means does take a lot of time and is not GPU accelerated unfortunately. 6-8 hours per video does seem a bit excessive though, do you know which CPU is in the PC you are using for the extraction?

You can always use the uniform extraction if the long processing time is an issue for you, it probably won't notable reduce the quality of the extracted dataset.

Best,
Timo
