Evaluating the true potential of diffusion-based inpainting in a compression context

This new framework allows us a detailed analysis of the strengths and weaknesses of the three PDEs. Our investigation leads to surprising results: at low compression rates, the simple harmonic diffusion can surpass its more sophisticated PDE-based competitors and even JPEG2000. For high compression rates, we find that EED yields the best result due to its robust inpainting performance under suboptimal conditions.
