Clarification on how data is obtained

[humzaiqbal]

Hi, thanks a lot for the great repo! One question, I notice that in all.py you have the following line,

SceneSeg/lgss/src/data/all.py

Lines 107 to 110 in 94c3a9e

	shotid_tmp = 0
	for shotid in shotid_list:
	if int(shotid) < shotid_tmp+seq_len_half:
	continue

does that mean you only train / run inference on shots that can be fully covered by the window length divided by 2? (Ie the 1st and 2nd shot of a movie would not be trained on at all with a window size of 4 and half window size 2). Also if thats the case then what about the shots at the very end (the last and second to last shot with the same window sizes as above) Trying to understand how the data is fed into the model, thanks!

Yes @humzaiqbal, what you understand is right. Since we adopt sliding windows in our model, the very start and end cannot be handled. To handle them, it is suggested to train another model with a small sliding window to specially process these cases.
