Keywords

💡AI

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. In the context of the video, AI is the core technology behind the creation of realistic images and is used to generate human-like photographs through complex processes.

💡Photorealistic

Photorealistic refers to the creation of images or visuals that closely resemble photographs, achieving a high level of detail and realism. In the video, the goal is to produce photorealistic images using AI, which involves various models and techniques to ensure the output looks like a real photograph.

💡Model

In the context of AI and machine learning, a model refers to a system that is trained to process input data and produce accurate output predictions or decisions. The video mentions several types of models, such as '체크 포인트' and '로라', which are used to generate specific parts of the AI-generated images.

💡Stable Diffusion

Stable Diffusion is a type of AI model that utilizes diffusion processes to generate images or other types of media. It is known for its ability to produce high-quality, photorealistic images from textual descriptions. In the video, Stable Diffusion is likely one of the technologies used to create the images.

💡Web UI

Web UI stands for Web User Interface, which is the platform or medium through which users interact with a particular service or application over the internet. In the video, the speaker discusses the installation and use of Stable Diffusion through its Web UI, which allows users to generate images without the need for extensive technical knowledge.

💡Google Colab

Google Colab is a cloud-based platform offered by Google that allows users to run Python programs in a collaborative environment. It is often used for machine learning and data analysis tasks, as it provides free access to computing resources and GPU support.

💡Checkpoint

In the context of AI and machine learning, a checkpoint refers to a point during the training process where the model's state is saved. This saved state can be used to resume training or to infer new data without starting from scratch. The video mentions a '체크 포인트' file, which is a model checkpoint used for generating the overall image.

💡VAE

Variational Autoencoder (VAE) is a type of generative model that learns to encode and decode data, often used for image generation and compression. VAEs are capable of creating new data points that are similar to the training data, which makes them useful for post-processing images generated by AI.

💡Negative Prompt

A negative prompt, in the context of AI image generation, refers to a set of instructions or keywords that tell the AI what elements to avoid or exclude from the generated image. This helps guide the AI to create images that meet specific criteria by preventing unwanted features.

💡Sampling Method

Sampling method in AI image generation refers to the algorithmic approach used to select data points from the model's latent space to create an image. Different sampling methods can affect the quality and uniqueness of the generated images, with some methods producing more varied or higher-quality results.

💡CFG Scale

CFG Scale, or Control Flow Graph Scale, is a parameter in AI image generation that adjusts the level of control the user has over the AI's creativity. A lower CFG Scale gives the AI more freedom to deviate from the prompt, while a higher value constrains the AI to follow the prompt more closely.
