shre-db / Image-Compression-SVD

A web service for image compression using singular value decomposition (SVD).

Introduction

In a rapidly evolving digital landscape, where images are at the heart of communication and information sharing, we present ImageSVD – a cutting-edge image compression solution powered by singular value decomposition (SVD). This project demonstrates the fusion of data science and mathematical techniques to address a critical challenge in the digital age: efficient image storage and transmission.

The Business Challenge

In today's data-driven world, the demand for efficient image compression techniques is ever-growing. High-quality images can consume substantial storage space and bandwidth, leading to slower web performance and increased costs. ImageSVD is our response to this challenge, offering an innovative approach to compressing images while preserving their essential visual information.

The Tech Stack

Our journey began with a careful selection of technologies that would enable us to tackle this problem effectively. Python, with its robust libraries and versatile ecosystem, emerged as the primary language for this project. We leveraged the power of Python to implement singular value decomposition, a mathematical technique that forms the core of our image compression solution.

Objective

ImageSVD aims to provide a practical and intuitive solution for image compression. At its core, the project revolves around the singular value decomposition, which breaks down an image into three key components: $U$ (Left Singular Vectors), $S$ (Singular Values), and $V^T$ (Right Singular Vectors). These components form the foundation for our compression algorithm.

Finding the Optimal Rank

The heart of ImageSVD is the quest to find the optimal rank. By experimenting with different rank values, we determine the right balance between image compression and quality preservation. The higher the rank, the closer the approximated image is to the original, and our project empowers users to explore this trade-off.

Results

ImageSVD doesn't stop at compression; it's about visualizing the transformation. We provide users with insights into the compression process:

Visualizing Singular Values

Our platform generates a logarithmic scale graph of singular values $\sigma_j$ vs. the index of singular values $j$. This graph offers a compelling visual representation of the relative importance of each singular value, allowing users to grasp how the compression process affects the image's information content.

Understanding Variance and Energy

Another graph showcases the cumulative sum vs. the index of singular values $j$. This visualization illuminates the contribution of each singular value to the total variance or energy of the image. Users can gauge how much of the image's essence is retained by including specific singular values in the compression process.

Real-world Applications

Beyond the technical intricacies, ImageSVD has real-world applications. As data scientists, we understand the practicality of image compression in industries such as:

• Web Development: Optimize web page load times by reducing image sizes.
• Storage Solutions: Efficiently store and transmit large collections of images.
• Data Transfer: Minimize bandwidth usage in image-heavy applications.
