Keywords

💡Stable Diffusion

Stable Diffusion refers to a type of artificial intelligence model that generates images from textual descriptions. It is a part of the larger field of AI known as 'diffusion models,' which are capable of creating highly realistic images. In the video, Stable Diffusion is used to create photorealistic images on a personal computer using specific prompts and models.

💡Photorealism

Photorealism in the context of AI image generation means creating images that closely resemble photographs. It is a quality that the video aims to achieve by using Stable Diffusion with carefully crafted prompts. The script mentions the difficulty of achieving photorealism and provides methods to enhance the realism of AI-generated images.

💡Prompts

In AI image generation, prompts are the textual descriptions or commands that guide the AI in creating an image. They are crucial for directing the AI to produce the desired aesthetic or subject matter. The video emphasizes the importance of both positive prompts, which specify what to include, and negative prompts, which specify what to avoid.

💡Negative Prompt

A negative prompt is a directive given to an AI to exclude certain elements from the generated image. It serves as a constraint to refine the output, ensuring that unwanted features are not included. The script uses the term to illustrate how to guide the AI to create images with specific characteristics by avoiding others.

💡Neural Network

A neural network is a set of algorithms modeled loosely after the human brain that are designed to recognize patterns. In the context of the video, the neural network is the AI's underlying technology that interprets prompts to generate images. The script explains how the neural network uses prompts as 'guide rails' to construct the desired image.

💡Checkpoints

In the video, checkpoints refer to the different versions of the Stable Diffusion model, each trained on different datasets. These checkpoints can be layered with additional images to modify the output's aesthetic. The script mentions downloading and using specific checkpoints from websites like civetai.com to achieve desired visual effects.

💡Aesthetics

Aesthetics in this context refers to the visual style or the 'look' that the AI-generated images are intended to have. The video discusses how different checkpoints can produce different aesthetics, and how users can select and layer these to influence the final image's style.

💡Invoke AI

Invoke AI appears to be the software interface used in the video to interact with the Stable Diffusion model. It is through Invoke AI that the user can load models, enter prompts, and generate images. The script demonstrates using Invoke AI to select models and generate images based on the provided prompts.

💡Cyberpunk

Cyberpunk is a genre of science fiction that features advanced technological and scientific achievements, juxtaposed with a degree of breakdown or radical change in the social order. In the video, cyberpunk is used as an aesthetic choice for the AI to generate images with a futuristic, dystopian vibe, as demonstrated with the examples of a 'cyberpunk city' and 'cyberpunk car.'

💡Upscaling

Upscaling in the context of image generation refers to the process of increasing the resolution of an image without losing quality. The video mentions using the 'send to image to image' feature in Invoke AI to upscale images by 4X, maintaining the same aesthetic and details but at a higher resolution.
