Reverse-Engineered Stable Diffusion: Image-Based Prompt Generation

This repository showcases a project where stable diffusion techniques are reverse-engineered to generate image-based prompts. By integrating advanced deep learning models such as ViT, CLIP, and BLIP, the project demonstrates a robust framework for leveraging these models collaboratively. The work also explores loss computation techniques to refine the generated outputs.

Features

  • Reverse Engineering Stable Diffusion: Explores the mechanics of stable diffusion and attempts to reverse it for generating image prompts.
  • Model Integration: Combines Vision Transformer (ViT), CLIP, and BLIP for feature extraction and semantic analysis.
  • Loss Computation: Implements loss functions to optimize the reverse-generation process.
  • Advanced Tech Stack: Developed using Python and PyTorch for seamless integration with deep learning models.

Tech Stack

  • Programming Language: Python
  • Framework: PyTorch
  • Models:
    • BLIP: Bootstrapped Language-Image Pretraining for image-caption tasks.
    • ViT: Vision Transformer for image recognition.
    • CLIP: Contrastive Language–Image Pretraining for linking text and images.
  • Libraries: Deep learning utilities and stable diffusion libraries.

Requirements

  • Python 3.8+
  • PyTorch 1.10+
  • BLIP, ViT, and CLIP model weights (Download instructions provided below)
  • Other dependencies: 
    pip install -r requirements.txt

How It Works

  1. Input Image Processing: The image is preprocessed and passed through the ViT model to extract features.
  2. Language-Image Alignment: CLIP links the extracted image features to text embeddings.
  3. Prompt Generation: BLIP generates text-based prompts from the image features.
  4. Loss Computation: The generated prompts are evaluated, and the model adjusts outputs to minimize loss.

Results

The project successfully demonstrates prompt generation from images using a reverse-engineered stable diffusion pipeline. Further refinements and experiments with loss functions can enhance the model's accuracy.

Future Work

  • Experiment with alternative diffusion models.
  • Optimize the loss function for improved prompt accuracy.
  • Expand the dataset for better generalization.
