Extreme compression of grayscale images

TL;DR

This paper explores the limits of extreme grayscale image compression ratios exceeding 50:1 using a novel V-variable image compression method, aiming to understand how well images can be stored under such high compression.

Contribution

Introduces a new V-variable image compression technique specifically designed for extreme compression ratios in grayscale images.

Findings

Achieves high-quality image reconstruction at compression ratios greater than 50:1.

Demonstrates the effectiveness of V-variable compression in extreme cases.

Provides insights into the potential and limitations of extreme image compression.

Abstract

Given an grayscale digital image, and a positive integer $n$, how well can we store the image at a compression ratio of $n:1$? In this paper we address the above question in extreme cases when $n>>50$ using "$\mathbf{V}$-variable image compression".
