AI systems can create realistic images from text descriptions

Artificial intelligence has come a long way in the past few years. Recently, multimodal learning, such as text-to-image synthesis and image-text contrastive learning, has transformed the research community and captured widespread public interest. In particular, neural networks have been successfully used for creative image generation and editing applications.

AI systems can be used to create images from text descriptions used as input, so-called “text-to-image” generators. They take a text prompt in natural language to create an image based on that description.

Text-to-Image technology has progressed significantly in the past few years. In 2022, the newly released AI generators such as DALL-E 2 from Open AI and Imagen AI from Google Research are able to achieve significantly better results and generate photorealistic images with AI.

What is AI-generated art?

AI-generated art describes art that is created by a computer or machine learning algorithm, as opposed to a human. Art created using artificial intelligence can include images or sculptures that are generated based on a text description.

This type of art can be incredibly realistic and lifelike, sometimes fooling people into thinking that it is a photograph. However, AI-generated art can also be quite abstract, with no real resemblance to the real world or imitate characteristic art styles of famous painters.

One of the benefits of AI art is that it is often created by algorithms that are designed to mimic the way humans create art. This means that AI-generated art can be used to study how humans create and perceive art. It can also be used to create art that is specifically designed to appeal to human emotions and sensibilities.

AI-generated art is also a great way to create unique and personalized artwork. Because each AI system is different, the results that they produce will be unique. This means that you can have a one-of-a-kind piece of artwork that is created specifically for you.

How can I generate AI generated images?

For example, you could provide a text description such as “An astronaut riding a horse in photorealistic style” and select the desired output image size and format. After selecting the “Generate” button, the Text-to-Image system will then create a realistic image based on the text description.

If you would change it to “An astronaut riding a horse as a pencil drawing,” the output would be completely different and show a generated image of a pencil drawing. Every generated instance is completely unique, even if the text prompts are identical.

The most popular AI image generators

There are different AI systems that use different techniques and text-to-image models. The most recent ones provide significantly higher image quality and more accurate results.

DALL-E and DALL-E 2 (2022)

Dall-E is an AI system created by OpenAI that can generate images from textual descriptions, introduced in a blog post on January 05, 2021. Named after the Spanish surrealist artist Salvador Dalí and Pixar’s science fiction robot WALL·E, DALL·E combines artistic creativity with the automation of a bot.

The AI system uses a 12-billion parameter training version of the GPT-3 transformer model to interpret the natural language inputs and generate corresponding images. DALL-E is capable of creating anthropomorphized (human-like) animals and objects, text rendering, transforming existing images, and combining objects and concepts in one image. It can also complete missing pieces of an image.

DALL-E 2 is a more sophisticated AI system that was released in 2022. It is able to generate photorealistic images with better results than the first version. Additionally, it can complete missing pieces of an image, which was not possible with the first version. DALL-E 2 is one of the best performing image generators available right now, only surpassed by Imagen & Parti (FID of 7.3).

GANpaint

GANpaint is a text-to-image system that can generate images based on textual descriptions, released in a research paper in December 2020. The system is based on Generative Adversarial Networks (GANs) and uses a dataset of 50,000 paintings to learn the mapping between textual descriptions and visual images.

DeepArt.io

DeepArt.io is a website that allows users to generate artistic images from textual descriptions, using a deep learning system. The website provides a user interface that allows users to input text and then generate corresponding images. DeepArt.io uses a pre-trained neural network model to interpret the natural language inputs and generate corresponding images.

Imagen AI (2022)

Imagen AI is an AI system that creates photorealistic images from input text, it was developed by Google Research. Imagen is a text-to-image diffusion model that achieves an unprecedented degree of photorealism and a deep level of natural language understanding.

The platform has two main components: a neural network for generating images, and a natural language processing system for understanding text descriptions.

Imagen’s text-to-image model achieves a new state-of-the-art FID score of 7.27 on the COCO dataset, without ever training on COCO. In tests, humans rated Imagen sample outputs to be on par with reference images of COCO data itself. This implies, that this system can be used to generate training data for computer vision algorithms that are popularly trained on the COCO dataset.

The image and photos generated by AI are impressively realistic. Some output samples are so realistic that it is impossible for humans to tell whether it was generated by an AI model or captured by a camera.

Comparison of the best AI image generators

Imagen consists of a text encoder that maps text to a sequence of embeddings and a cascade of conditional diffusion models that map these embeddings to images of increasing resolutions. Get the official research paper here.

Imagen comprises a Frozen T5-XXL encoder to map input text into a sequence of embeddings and a 64×64 image diffusion model, followed by two super-resolution diffusion models for generating 256×256 and 1024×1024 images. All diffusion models are conditioned on the text embedding sequence and use classifier-free guidance.

Imagen relies on new sampling techniques that allow usage of large guidance weights without sample quality degradation observed in prior work. This makes it possible to generate images with higher fidelity and better image-text alignments than previously possible.

Benchmark Comparison (Zero-Shot FID-30K)

The Imagen system outperforms other methods on COCO with zero-shot FID-30K of 7.27 (lower is better). On this benchmark, it significantly outperforms other engines such as GLIDE (12.4) and the concurrent work of DALL-E 2 (at 10.4).

  • DALL-E 17.89
  • LAFITE 26.94
  • GLIDE 12.24
  • DALL-E 2 10.39
  • Imagen 7.27

Limitations of an AI image generator

Cutting-edge AI image generation models are able to provide spectacular results. However, they are not flawless and limited in some instances. Even the most advanced AI systems DALL-E 2 and Imagen sometimes produce blurry outputs or images with incorrect colors.

Also, they can only create images from text descriptions in natural language, and cannot interpret highly complex commands or large amounts of detailed text. The images such AI systems generate are not always realistic, and can sometimes be very abstract or heavily distorted.

It’s important to note that the technology is very new and not yet production-ready. However, despite these limitations, the performance of modern image and photo generation systems is still very impressive and marks a great step forward in text-to-image research.

Test out an online AI image generator

There are different ways how you can test AI model-based image generation yourself and with your own text prompts.

  • DALL-E mini (Craiyon): If you want to try out the AI art service yourself, you can do so on the Dall-E mini website that was not renamed to Craiyon. There you’ll be asked to enter a prompt and run it. The generation process can take a while, so expect a wait of up to 2 minutes for your image to appear. While DALL-E 2 is now in closed beta, you can use the DALL-E Mini application, an open-source version of the original AI model that is available for public use.
  • NightCafe Creator: NightCafe Creator is an AI Art Generator application that provides several methods of generating Art with AI from nothing but a text prompt.
  • WOMBO Dream: This AI-powered artwork tool can be used to create different images by picking an art style and entering a text prompt.

Real-world applications and benefits of AI to generate images

In the near future, there are many areas where an ai image generator can be of use, for example in marketing, e-commerce, city planning, computer vision, and so on. Some practical use cases include:

  • Marketing: AI-generated images can be used for websites or advertising materials. This helps to create more realistic and appealing visuals or generate custom graphics or print media for a specific audience. The automation aspect leads to immense time savings in searching for or creating pictures.
