#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

| var SUM pseudocode: add up all the numbers in an array | |
| var MEAN pseudocode: divide the sum of an array by the length of that array. | |
| Var MEDIAN pseudocode: use array.sort to order the numbers in our array from smallest to lartest | |
| then (if array length is odd): find the midpoint of that array | |
| or (if array length is even): find the two numbers that sit on either side of array.length/2 |
