| #Alright, so this should automatically convert a given video into a gif called optimized_output.gif | |
| # See here for explanation: https://github.com/lelandbatey/configDebDev/blob/master/helpFiles.txt#L113 | |
| ffmpeg -i $1 out%04d.gif # Extracts each frame of the video as a single gif | |
| convert -delay 4 out*.gif anim.gif # Combines all the frames into one very nicely animated gif. | |
| convert -layers Optimize anim.gif optimized_output.gif # Optimizes the gif using imagemagick | |
| # vvvvv Cleans up the leftovers |
This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert $1 -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 $2
