In short, the transformation in the way we utilise generative AI has already begun. Neural networks being the core of most of these developments, various tools are available today for creative image generation. 

These applications are capable of converting text description into ready to use images, aka, text-to-image generators. Users simply provide the text prompt in natural language while the apps turn those instrustion into images.

Solutions such as Open AI, DALL-E provide significantly precise and accurate outputs as photorealistic images. 

AI Generated Images – Explained!

As you would expect, AI-generated images aren’t by humans. Instead, with the help of machine learning algorithms, anyone with no prior art experience can create realistic images. 

These work of art by AI includes various formats such as images, sculptures, videos and others. And all this happens with a text description. 

The good news is, unlike before, these images made by generative AI are incredibly realistic. However, the outputs are not always consistent and can even feel abstract and far away from any resemblance to the real world. 

So, how is it making a difference?

Well, generative AI works on algorithms that aim at mimicing the way humans create art. Thus, these images or art work by AI can become a huge asset for studying human’s mind and how they perceive art. 

In addition, these AI tools can produce images or other arts that appeal to human emotions. Enabling businesses to tap into the benefits of personalized artwork that could help grab attention faster. 

Brief Explanation of Deep Learning and its Role in Image Generation

Deep learning is a subfield of machine learning that focuses on training artificial neural networks to learn and make decisions based on large amounts of data. It involves training neural networks with multiple layers to extract complex patterns and representations from input data. In the context of image generation, deep learning plays a vital role in capturing the intricate details and generating realistic images.

Deep learning models, such as Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs), have revolutionized image generation. 

In both cases, deep learning models leverage the power of convolutional neural networks (CNNs) to extract hierarchical features and capture spatial dependencies in images. This enables the models to learn complex image representations and generate images that exhibit realistic textures, shapes, and structures.

Overall, deep learning has greatly advanced the field of image generation, pushing the boundaries of what AI systems can create. Its ability to learn from vast amounts of data and capture intricate details has paved the way for applications in art, computer graphics, data augmentation, and beyond.

How can I Create AI generated images?

Step 1: Choose an AI tool for image generation. You can refer to the various options mentioned in this article. Or choose anyone that you prefer from your personal list. 

Step 2: Get equipped with the prompts. Remember, unless you type in the write description, you won’t get the desired output. The best practice is to include the size and format of the required image along with the photo description. For instance, write a description – “a happy face of an old man in photorealistic style”. Make sure to choose the option for size and format of the image in the AI tools. 

Step 3: You might need to repeat your prompts with few changes, depending on the results you receive. If you feel, you want something different, don’t forget to change the prompt accordingly. This is a test and trial process. With experience, you will become better at writing accurate prompts. 

How to Evaluate Image Generation for Accuracy?

Evaluation in image generation involves assessing the quality and fidelity of generated images produced by AI models. This is crucial in determining the performance of image generation algorithms. Thus, helping researchers and practitioners compare different models, identify strengths and weaknesses, and drive advancements in the field. 

However, evaluating AI images isn’t an easy job. This is due to the subjective nature of visual perception and the lack of a definitive ground truth for comparison.

Thankfully, there are a few metrics that help evaluate the quality of generated images. 

Inception Score (IS) measures the diversity and quality of generated samples by considering both the confidence of the model in its predictions and the diversity of predicted labels. 

Fréchet Inception Distance (FID), on the other hand evaluates the similarity between the distribution of real and generated images in a feature space derived from a pre-trained classifier network. 

Then there are perceptual similarity metrics – Structural Similarity Index (SSIM) and Peak Signal-to-Noise Ratio (PSNR). These assess the similarity between generated and real images based on perceptual cues.

Please note, these metrics have their own limitations. And their results may not always align with human perception. Evaluating image generation also involves subjective assessment through human evaluation, where individuals rate the quality, realism, and visual appeal of generated images. User studies, surveys, and pairwise comparisons can provide valuable insights into the strengths and weaknesses of different models.

Limitations of AI Image Generator

Generating realistic images with AI poses several challenges that researchers and practitioners continue to address:

Uncanny Valley Effect

One of the primary challenges is overcoming the “uncanny valley” effect, where generated images look almost real but still exhibit subtle flaws that make them appear eerie or unnatural. 

Handling High-Resolution Images

Generating high-resolution images with fine details requires complex models and significant computational resources. Scaling up the image generation process without sacrificing quality poses challenges in terms of memory requirements, training time, and model stability.

Preserving Semantic Consistency

Generating realistic images that adhere to the desired semantic content and context can be difficult. Ensuring that generated images maintain the intended objects, structures, and scene composition while incorporating variations and details is still an ongoing challenge.

Training Data Bias

Biases present in the training data, such as underrepresentation of certain demographics or overemphasis on specific visual patterns, can result in biased or skewed outputs. 

Ethical Considerations 

Generating realistic images with AI raises ethical concerns, particularly in the context of deepfakes and malicious use. 

Addressing these challenges requires ongoing research and development in areas such as model architecture design, loss functions, regularization techniques, data curation, and ethical frameworks. Hopefully, we might see these challenges vanish with continuous development in the field of generative AI.
