## Pseudo code for counting iterations of 1 and 0 as listed on new lines in a .txt

##PREPARATION WORK**
name input_file
	input_file = “C:\Video_Forensics\case_number_CV000001\frame3000-12034.txt”
##  this is where the script should be modified to tailor to a specific case or workstation

Create file “iterations1.txt”
##	this is the file that will be the new list counting the consecutive iterations of 1
create file “iterations0.txt”
##	this is the file that will be the new list counting the consecutive iterations of 0

create object_1count
	object_1count=0
##  this will count the number of times that 1 has been read since the last number was 0
create object_0count
	object_0count=0
##  this will count the number of times that 0 has been read since the last number was 1

open read-only file input_file
	##  Open as read-only to avoid disturbing the integrity of the data set
	##  This file should have only a 1 or a 0 written once on each line and be a .txt file
	##  It should not be difficult to convert .csv or .xls to .txt

read line number 1 of input_file

If value=1,
	run loop1test.
else if value=0,
	run loop0test.


(loop1test)
##  this loop initiates the logic chain when the data set starts with a 1 and will be 0 when it changes
	set object_1count=( object_1count + 1)
##  now the program is counting iterations of 1
	run 1start_count_loop	
(end loop1test)
