With our article, we will help you dive deep into the world of AI image generation and make you understand the core methodologies that are fueling it, some applications and limitations involved with it, and finally, discuss the future of AI image generation.

What is AI Image Generation?

AI image generation is the process of generating images by utilizing advanced machine learning algorithms like Generative Adversarial Networks and diffusion models. For providing AI-generated images, these models function by analyzing and understanding complex underlying patterns within the provided training dataset, and eventually learns to provide realistic or stylized visuals from inputs like text prompts, semantic maps, or noise vectors.

By combining natural language processing methodologies with computer vision techniques, it essentially provides AI-generated images for artwork, concept designs, and visual assets for different industries, such as entertainment, marketing, fashion, and gaming.

Why is the need for AI Image Generation rising?

The need for AI image generation is rising as industries have to cover the demands of the evolving market trends. As with AI-powered image generation tools, industries can get fast, cost-effective, and scalable visual content. With tools like this, industries can reduce the need for redundant manual efforts of creating an image from scratch, as they can get it generated within minutes by providing simple prompts.

Through these AI image generation tools, industries as well as individuals can have creative freedom to produce customized digital content while remaining consistent with the brand tone, guidelines, and standards. The potential of generative AI models is better explained in the words of Andrej Karpathy(former Director of AI at Tesla):

"Generative models are the most exciting frontier in AI. They don't just analyze the world — they create new worlds."

While this quote highlights the essential positioning of generative AI models, it also reflects that in the future, they will not be functioning as a methodology for performing analysis only, but also providing useful, refined content.

Methodologies for AI Image Generation

To empower a large range of industrial applications, we have different models that provide their specific capabilities for the AI image generation ecosystem. For your understanding, we have enlisted some of the prominent methodologies for AI image generation:

Generative Adversarial Networks (GANs)

Generative Adversarial Networks, or GANs, are one of the most essential methodologies in AI image generation. It works with a combination of two competing neural networks, the generator and discriminator. Here, the generator is responsible for generating realistic images by learning from the training data. In contrast, the discriminator networks work to evaluate whether the generated image by the generator is real or fake. This adversarial network encourages the generator to improve its performance until it can produce images which is indistinguishable from the real ones for the discriminator to differentiate from the real ones.

The GANs exhibit exceptional performance in generating high-resolution, realistic images. However, they can get unstable during training and might struggle with mode collapse, in which the generator starts generating limited variations for images.

Use case:

Despite this limitation, GANs are still very commonly used for AI image generation tasks, especially for use cases like deepfakes, face generation, and artistic style transfer.

Example: StyleGAN by NVIDIA

StyleGAN is an advanced AI image generation model. It generates highly realistic images by differentiating the style elements like shape and texture. It integrates a mapping network and adaptive normalization (AdaIN) to ensure enhanced detailings at different levels, which provides precise layer manipulation to generate realistic images.

Diffusion Models

The diffusion model is a significant methodology in AI image generation, known for its ability to produce high-quality, detailed visuals. Technically, diffusion models work by simulating a two-phase process. First, during training, they perform a forward diffusion process, where clean images are gradually corrupted with noise over many time steps, typically following a Markov process. The model is then trained to learn the reverse diffusion, a denoising process that reconstructs the original image from this noisy data.

During inference, image generation begins from pure noise and proceeds iteratively through the learned reverse process to produce a realistic image. This structured approach allows for fine-grained control over image details. However, diffusion models tend to be slower than GANs due to their multi-step generation process, though they offer superior stability and semantic alignment in outputs.

Use case:

Diffusion models are commonly used for AI image generation tasks that involve text-to-image generation or image in painting, since they have more stable and precise control over the visual content they are generating.

Example: DALL-E 2 by OpenAI

DALL-E 2 incorporates diffusion models to generate images. It begins the process of image generation with a random, noisy image, which slowly refines into a visual with particular details by going through the process of denoising. It's further guided by the integrated CLIP model that aligns the image with the given text prompt, allowing it to generate semantically accurate images.

Transformer-Based Models

The transformer models are also being utilised for AI image generation, though they are more commonly used for natural language processing tasks. However, by taking inspiration from language processing tasks, these transformer models can also be used for AI image generation tasks. For performing image generation, it treats both texts and image generation as a sequence of tokens.

It utilizes an attention mechanism to learn deep semantic relationships between the text and visual features. They generate the required images by understanding the text-based prompts and aligning them with the visual content. However, these models require to be trained on large datasets, and demand major computing resources, which are the elements that might restrict their speed and overall performance.

Use case:

The transformer model can play an essential role in image generation applications where semantic alignment between the text and image is required, as it holds a specialized ability to generate such visuals.

Example: Imagen by Google

Imagen by Google utilizes large transformer-based language models to translate the text prompts into high-quality visual representations. This works by mapping the text prompt into a detailed embedding space, which further guides the diffusion model to generate images, with its combination enriches the semantic understanding, ultimately improving the visual results.

Variational Autoencoders (VAEs)

A Variational Autoencoder model can be used for AI image generation. Since it offers a more structured and easily interpretable way to generate images. It encodes the inputs and represents them in a latent space, and then further decodes them back. However, these VAEs are probabilistic models that allow them to generate multiple variations by using the same latent space, which makes them different from GANs and diffusion models.

Although the visuals produced by VAEs might not be as sharp as other models, they are computationally very efficient and convenient to train, which makes them a good approach for the AI image generation task where computational resources are limited.

Use Cases:

VAEs can be used for tasks that require interpolation, morphing, data compression, image reconstruction, or style transfer. By integrating these with other architectures, we can introduce more realism and control within the generated image content.

Example: VQ-VAE

VQ-VAE (Vector Quantized Variational Autoencoder) works by compressing images into discrete codebook tokens and further creating a compact latent space. The Diffusion models then function lower-dimensional space, to make generation efficient. This results in more resource-friendly image generation.

CLIP-Guided Generation

CLIP (Contrastive Language–Image Pre-training) is a model introduced by OpenAI, which is not essentially a generative model on its own but plays a key role in guiding image generation pipelines. CLIP operates by learning to combine representations of text and images, enabling it to evaluate how well a generated image matches the provided prompt.

While CLIP is a powerful multimodal embedding model developed to bridge text and image understanding by mapping them into a shared latent space. But it isn't a generative model itself, CLIP plays a crucial role in guiding image generation models like VQGAN and diffusion models by evaluating how well the generated images align with the input prompts. This enables more semantically accurate and contextually relevant visuals. However, its performance may weaken with abstract or highly interpretive prompts, sometimes leading to less coherent outputs.

Use Case:

The CLIP model has a great ability to enable highly accurate prompt-based image generation. So, this can specifically be used for use cases like prompt engineering or refining diffusion output.

Example: DALL·E by OpenAI

DALL-E by OpenAI implements the CLIP model to evaluate and guide image generation, making sure that the generated output aligns well with input text. Scoring the generated images based on their closeness to the provided prompt refines the quality of the final output image.
