Parallel Computing

This repository stores the project for the course Parallel and Distributed Computing at the Universidad Nacional De Colombia.

This project aims to test different ways to parallelize a algorithm to downsample images in 720p, 1080p and 4K to 480p.

How to use

First of all, you need to install OpenCV for C++: How to install

When dependencies are install, to compile the code:

g++ image_scaling.cpp -o image_scaling -std=c++11 `pkg-config --cflags --libs opencv` -lpthread

To run:

./image_scaling ./image1_720p.jpg ./result.jpg 4 Nearest

run script:

bash script.sh

This accepts 3 parameters:

1. Source input image path.
2. Result image path.
3. Number of threads.
4. Algorithm - Nearest / Bilinear
