Re-Filtering missed frames

#!/bin/bash

# Still a work in progress!

#   Pseudocode:

#   Go to the folder NIH2018_Data/Video
#   for s from 1 to 5:
#           Enter the folder /Session + s + /
#           for every file ending with the .MP4 extension
#               Split the file name by "_" and store the first string in a var called name
#               if name starts with "p0"
#                   cd to /Users/$USER/Desktop/ExtractedVidFrames/Banneker/Session$s/$name
#               else if name starts with "p1"
#                   cd to /Users/$USER/Desktop/ExtractedVidFrames/JFK/Session$s/$name
#               else
#                   cd to /Users/$USER/Desktop/ExtractedVidFrames/Unknown/Session$s/$name
#
#               for every subfolder:
#                   check if "training.txt" exists in the folder and store bool in var called "filtered"
#                   if filtered is false:
#                       run Filtering program to filter the newly created frames (thus saving space)
#                       echo Re-filtered $fileName!
#                   else
#                       echo $fileName is already filtered
#           echo Done with Session $s!

# Note: this script requires the following programs to be installed and aliased:
# ffmpeg as ffmpeg
# ffprobe as ffprobe
# c# as dotnet
