Why only use the even line of data in data_util

[LittleFlyFish]

I noticed in the data_util. This method only selects the even line of the original data into the training data and test data. I don't quite understand that. I was thought to directly select all the lines. Besides, in the data n /time d in txt file, is n means there are n frames?

    even_list = range(0, n, 2)

Is that means down sample the original data ? such as changes 50 Hz into 25Hz ? @una-dinosauria

Hi,

Yes, this downsamples from 50Hz to 25Hz. It is also in line with the previous work of Jain et al. CVPR 16 -- we took the data from them and most of the preprocessing code as well.

Cheers,

Thank you very much ! It is very helpful !

Hi @una-dinosauria
Why do you think the data is downsampled?
Is it to conserve memory?
