Image Processing and Compression Library

Overview

This library aims to provide its users with basic image processing operations along with ways to compress the images. Currently the following operations are supported:

1. RGB to Grayscale
2. Horizontal and Vertical Flip

Support for more operations are welcome!

Image Compression

Image compression is done using the k-means algorithm, pixel values are grouped together to form bands of pixels, hence making it more compressable for JPEG and other methods of compression.

How to set up

Note: You need to have GCC version > 10.2.0

1. Clone the repo with git clone https://github.com/DebadityaPal/k-means-compressor
2. Run the software with CLI commands The CLI commands are:

g++ compressor.cpp -o compressor

compressor <args>

Usage

The arguments are listed below

Usage:
