What is Image Generation AI?

Image generation AI is AI that generates images (text-to-image) from text.

In other words, by issuing instructions for what kind of image to be created from text, the AI will create an image that matches the command.

Image Generative AI is one of Generative AI.

AI Chatbot is a text creation AI in Generative AI.

Main Technologies Used in Image Generation AI

This section introduces the main technologies used in image generation AI.

NOTE: Variational Autoencoder (VAE), Autoregressive Model, and other models used in image generation AI.

Generative Adversarial Networks (GANs)

Generative Adversarial Networks (GANs) are a method of generating new images using two neural networks, a Generator and a Discriminator.

The Generator starts with random noise and tries to generate an image.

The Discriminator is trained to distinguish between the image generated by the Generator and the real image.

The Generator repeats the training so that it does not judge the image generated by the Discriminator as a fake.

This training is repeated until the Generator is able to produce an image that is close to the real image.

Applications of GANs include image restoration, super-resolution, and image transformation, as well as image generation.

These are explanatory videos of GANs by Ian Goodfellow, the proponent of GANs (slides).

Diffusion Model

Diffusion Model is a diffusion probabilistic model used in image generation AI.

The paper on Diffusion Models is "Denoising Diffusion Probabilistic Model".

These are explanatory videos of Diffusion Model.

Representative Software for Image Generation AI

The following is a list of typical image generation AI software.

These software mainly use Diffusion Models.

DALL-E

DALL-E is an image generation AI developed by OpenAI.

The versions of DALL-E are as follows

  • 2021: Release DALL-E
  • 2022: Release DALL-E 2
  • 2023: Release DALL-E 3

These are explanatory videos of DALL-E.

Midjourney

Midjourney is an image generation AI developed by Midjourney, Inc. in 2022.

Midjourney made headlines when it was used to deepfake Donald Trump in March 2023.

These are explanatory videos of Midjourney.

Stable Diffusion

Stable Diffusion is an image generation AI developed by Robin Rombach and Andreas Blattmann at Ludwig Maximilian University Munich in 2022.

Stable Diffusion makes it easy to create your own images for use in articles.

These are explanatory videos of Stable Diffusion.

Stable Diffusion is easily available at the following.

Adobe Firefly

Adobe Firefly is an image generation AI provided by Adobe.

These are explanatory videos of Adobe Firefly.

Bing Image Creator

Bing Image Creator is an image generation AI of Bing.

These are explanatory videos of Bing Image Creator.

Leonardo.Ai

Leonardo.Ai is an image generation AI that can generate up to 150 images per day for free.

In addition, Leonardo.Ai can be used commercially.

These are explanatory videos of Leonardo.Ai.

Summary

We introduced Image Generation AI and representative software.

Representative software for image generation AI is DALL-E, Midjourney, and Stable Diffusion!
