First frame of video/camera is presented to the user to select the box where your eyes it. Use mouse to left-click at a point, drag the cursor to another point, and release the left-button. You won't see a box unless you are done dragging. Once box is visible press q. The process will start.

blinky.py

Process a given video for blinks. Very fast.

python blinky.py -f video_file.webm
Select a region on frame where eye it.
Let it run till video is over. A csv files will be produced with blink location. Two algorithms are used: one based on edge detection and other one is based on couting dark-pixals.

Error on using blinky_gui.py

Hello Dilawar, I am trying to run your blinky_gui.py code on Ubuntu16.04 using virtual environment with Python 3.5 and OpenCv 3.3. version. I am taking one .mp4 file as video input. On running I am getting this error.

Can you please help me with this.

A lot of issues with avi format.

Raspberry Pi

I am trying to use your code for raspberry pi but i am getting stuck in importing the files itself,
i cant import the extract and webcam file in the blink.py, i have tried whatever i could find

blinky_webcam.py

when i try to execute blinky_webcam.py in ubuntu, I am getting this error
[WARN] failed to get FPS. Setting to 15
[ERR] Failed to get blinks: fileno

Output

I'm not really sure I understand the output. Could you explain the two files that are output, what the columns mean, what the units are, etc.

I received two output files for a 30 second video but the "# time" column in one file goes up to 8 seconds and the "# time" column in the other only goes up to 12 and has 291 rows. Can you explain this?
