  1. Foundations of Digital Imaging & Python

    4 weeks
    Goals
    • Understand core digital image concepts (pixels, resolution, color spaces)
    • Set up a Python environment and learn essential libraries (OpenCV, Pillow)
    • Grasp the basics of command-line operations and virtual environments
    Resources
    • Coursera: 'Image and Video Processing' by Duke University
    • Real Python: OpenCV tutorials
    • Kaggle: 'Python' micro-course
    Milestone

    Can write a Python script to load, resize (naively), and save an image, and explain the difference between linear and perceptual color spaces.

  2. Introduction to AI Super-Resolution

    6 weeks
    Goals
    • Learn the theory behind super-resolution (SR) and its history
    • Get hands-on with a state-of-the-art pre-trained SR model (e.g., Real-ESRGAN)
    • Understand the role of loss functions (perceptual, adversarial) in training
    Resources
    • Paper: 'ESRGAN: Enhanced Super-Resolution Generative Adversarial Networks'
    • GitHub: 'xinntao/Real-ESRGAN' repository and its documentation
    • YouTube: Simplified explainers on SRGANs and ESRGAN
    Milestone

    Can successfully upscale a batch of diverse low-res images using the CLI of Real-ESRGAN, evaluate results visually, and articulate why it's better than bicubic interpolation.

  3. Advanced Tools, Fine-Tuning & Deployment

    8 weeks
    Goals
    • Learn to prepare custom datasets and fine-tune an SR model
    • Explore diffusion-based upscalers and their integration (e.g., via Hugging Face)
    • Build a basic processing pipeline and deploy it to a cloud service
    Resources
    • Hugging Face Diffusers documentation (for upscaler examples)
    • Kaggle competitions or datasets related to image restoration
    • AWS/GCP tutorials on launching GPU instances for ML inference
    Milestone

    Can fine-tune a pre-trained SR model on a small custom dataset (e.g., vintage photos) and create a simple Gradio web interface to upscale uploaded images.

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Vintage Photo Restoration Suite

Beginner

Build a Python script that takes a folder of old, low-resolution photos (e.g., family albums), applies a pre-trained Real-ESRGAN model to upscale them, and uses OpenCV to perform basic denoising and color correction. The goal is to create a ready-to-use tool for personal archiving.

Anime Art Upscaler with Fine-Tuning

Intermediate

Create a custom dataset of high-resolution and synthetically degraded anime art. Fine-tune a lightweight SR model (like a smaller ESRGAN variant) on this dataset. Build a simple Gradio web app where users can upload anime screenshots and get enhanced versions, demonstrating the improvement over the general model.

E-commerce Product Image Pipeline on the Cloud

Advanced

Design and deploy an end-to-end system: Users upload product images via a web form (Flask/FastAPI). The backend queues the job, sends the image to an AWS GPU instance (e.g., a P3 or G4 instance) running a containerized upscaling model. The processed image is stored in S3, and a link is returned. Implement basic abuse detection and cost monitoring.
