Output about eye-blink-detector HOT 6 CLOSED

Both algorithms computes every time N and M entries have been added to their input timeseries. When the process terminates, last N and M entries are not written to result file. For examples, if your video was 300 seconds long, files will contain (300-24) seconds and (300-18) seconds - given that fps does not change.

I'll leave this issue open to be fixed later.

I'm sorry but I'm a bit confused by this. What are N and M? Where did you get 24 and 18 from? The webm video I made is a looped video where the person blinks twice two seconds in, then nothing for six seconds, 2 blinks, nothing for six seconds, etc. Why are these the results? Here is a gif of the video I'm using https://gfycat.com/LightheartedSolidAfricanwilddog

What I'd like to get out of this tool is a csv with a list of times into the video indicating when a blink occured. Is this capable of doing that?

I just realized something that might be an insight to the problem. I get the following error:

Traceback (most recent call last):
    File "blinky.py", line 61, in <module>
        main(vars(args))
    File "blinky.py", line 35, in main

        bT, yy = t[x-1:-x], w[x-1:-x] - smoothW
ValueError: operands could not be broadcast together with shapes (0,) (75,)

I'm not sure what I did wrong. the webm file was saved in the same directory as blinky.py as eyetracker_test.webm and the command I run is:
python blinky.py -f eyetracker_test.webm

I tested the your video. Seems like opencv is having trouble converting it to grayscale after first few frames.

 $ ./blinky.py -f ~/Download/issue4.webm

Unfortunately I am short of time these days to test/reply quickly as I wish. Moreover, we are now moving this demo project into a real time system (with lab-rats); so most of the bugs is likely to be fixed in upcoming month.
