Description

Given a large collection of colours that represent a picture, compress the size of that data by grouping continuous sections of colours

Starting data
Green, green, green, blue, blue, red, red, red, black, black

Results in something like this
3 green, 2 blue, 3 red, 2 black

Include a simple way to show the colours, the size of the data (so the level of compression is known).

Convert a compressed image back to a normal one and display.

Research direction

The work is done when continuous colour runs can be compressed, the original and compressed data sizes can be shown, and the compressed form can be expanded and displayed again.
