About feature_extraction.py about VSUMM

[GreenD93]

Hi!

I have three questions about your code(feature_extraction.py).

1. I wondered why did you calculate hsv_histogram under 0.23 standard deviation? Although I read VSUMM paper, I was not able to find that thing. Rather, the paper showed "the standard deviation of monochromatic frames is equal to zero or a sufficiently small value close to zero".

2. You calculated HSV histogram with [0,256] range but in the case of hue, the range is [0,180]. Is it not a problem to calculate HSV histogram?

3. For histo_norm, you divided each value from a histogram by frams_size. Could you tell me about what's the meaning of frame_size and those contexts?

Thanks,
