Infinite zoom-in and zoom-out using Stable-diffusion-2

Have you ever attempted to zoom in on a photo on your smartphone, only to find it becoming pixelated and distorted? This happens because digital images are composed of a limited number of pixels, and when zoomed in excessively, the individual pixels become visible.

But what if there was a technique to create images that could be zoomed in on indefinitely without compromising quality? That’s precisely what the Stable Diffusion 2 technique ( a creation of Google AI) is attempting to accomplish.

Stable Diffusion 2 is a form of generative model that is trained on a collection of images. The model then learns to produce new images that resemble those in the dataset. However, unlike traditional generative models, Stable Diffusion 2 can generate images that can be zoomed in on infinitely without quality loss. This is possible because Stable Diffusion 2 utilizes a technique known as inpainting to fill in the missing pixels when an image is zoomed in. Inpainting is a technique used to replace missing or corrupted data. Next two sections provides brief introduction to these two techniques.

What is a diffusion model

Diffusion models are a class of generative models that learn to create images by adding noise and subsequently removing it. By training the model to eliminate noise, it becomes capable of generating new and unique images.

One way to conceptualize diffusion models is to envision starting with a blank image and gradually incorporating noise. The model then learns to eliminate the noise, resulting in an image that resembles the original but with some added noise elements. These models can produce a wide range of images, from realistic and abstract visuals to images derived from textual descriptions.

For instance, consider a dataset containing images of cats. A diffusion model trained on this dataset can generate new cat images that are both similar to the original dataset and uniquely creative. By employing this process, the model can create a diverse collection of images.

As an emerging type of generative model, diffusion models are still under development. Despite their relative novelty, they have demonstrated immense potential, promising to revolutionize the way images are generated in various fields. As research and development continue, diffusion models are expected to become even more sophisticated and versatile.

Inpainting

Inpainting is a technique used to replace missing or corrupted data in an image. When an image is zoomed out in the context of stable-diffusion-2-infinite-zoom-out, inpainting can be used to replace the absent pixels surrounding the image’s edges. While traditional inpainting techniques have been used for many years in image processing and computer vision, they often produce unrealistic results as they rely on statistical models to predict missing pixel values, which cannot always capture the complex patterns in natural images.

However, Stable Diffusion 2 uses a new inpainting algorithm based on a generative adversarial network (GAN), a type of neural network that generates realistic images. The inpainting GAN is trained on a dataset of images, and it learns to generate images that are similar to the original images but with missing pixels filled in.

The inpainting algorithm is a crucial aspect of Stable Diffusion 2, which enables the generation of images that can be infinitely zoomed in without losing quality. This is because the inpainting algorithm fills in the missing pixels when an image is zoomed in. For example, an inpainting algorithm can be used to repair a damaged image of a cat by filling in the missing pixels caused by a scratch, resulting in an almost original-quality image of the cat.

ArtGAN/stable-diffusion-2-infinite-zoom-out

At the core of ArtGAN/stable-diffusion-2-infinite-zoom-out is a diffusion process that commences with a random image and introduces minute amounts of noise incrementally. This noise integration is carefully engineered to enhance the image’s resemblance to real-world visuals. The model’s ability to generate infinitely zoomable images with unwavering visual stability is attributed to the “inpainting” technique described above. Inpainting serves to fill in missing or corrupted data, ensuring that images appear realistic even when subjected to extreme zoom-out conditions. You can try out the model at Hugging Face here.

Here is an example below where each zoom we do deep inside a painting.
