I found a whiteboard cleaning script which works well enough.

This is the script:

Code: Select all

convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
Original image:

This is the output (left is input, right is output):

Note how the last word 'TOUCHSCREEN' is more legible before processing. On the image processed the "E" in "TOUCHSCREEN" is not that crisp.
Can the processing be improved?

Perhaps you might be interested in my whiteboard script at my link below. It does require a Unix-like platform to run.
