Keywords

💡Photorealism

Photorealism refers to the creation of images that closely resemble real-life photographs in terms of detail and visual fidelity. In the context of the video, it is the primary goal of the AI models being discussed, aiming to produce images that look as if they could have been taken with a camera. The video emphasizes the progress made in achieving photorealistic results through the use of specific AI models and techniques.

💡Generative AI

Generative AI refers to artificial intelligence systems that are designed to generate new content, such as images, music, or text, based on patterns learned from existing data. In the video, generative AI is the underlying technology that enables the creation of photorealistic images through the use of models like Stable Diffusion and various 'lora' (layers of additional refinement).

💡Stable Diffusion

Stable Diffusion is an AI model used for generating images. It is mentioned in the video as the platform on which the journey to find the best photorealistic images is based. The video discusses the improvements and new models developed to enhance the photorealism of images generated by Stable Diffusion.

💡Model Training

Model training is the process of teaching an AI model to recognize and produce specific types of content by feeding it large amounts of data. In the video, it is mentioned that a new model has been trained specifically on realism, using stock photos of people to achieve more realistic portraits.

💡Skin Texture

Skin texture refers to the appearance and quality of the skin in an image, which is crucial for achieving photorealism. The video discusses the challenges of creating realistic skin textures in AI-generated images and how adding details like dry skin, skin fast, and visible skin hair can improve the realism of the portraits.

💡Eyes Detail

Eyes detail is the accuracy and complexity of the eye representation in an image. The video emphasizes the importance of detailed eyes for photorealistic portraits and introduces a 'detail eyes' model to enhance the eye features in the generated images.
