Proof-of-concept multithreaded Gaussian blur of PPM images using POSIX threads. Built and tested with GCC 9.3 on Ubuntu 20.04 and GCC 4.9 on Ubuntu 14.04.
To try it from the terminal, setup the viu terminal image viewer via cargo install viu. If you don't have cargo installed, visit rustup.rs to install it on your system.
Run make test to test against the included image (in images/small_orig.ppm). You should see the blurred image in your terminal.
Issues and PRs welcome!
