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:

| * DESCRIPTION: | |
| * This example demonstrates how to "wait" for thread completions by using | |
| * the Pthread join routine. Threads are explicitly created in a joinable | |
| * state for portability reasons. Use of the pthread_exit status argument is | |
| * also shown. Compare to detached.c | |
