💡Image to Image

Image to Image is a feature in AI image generation models like Stable Diffusion, which allows users to take an existing image and modify or enhance specific parts of it based on a textual prompt. This function enables users to blend the generated content seamlessly with the original image, creating a composite that maintains the overall context and style of the original while updating particular areas according to the user's requirements. In the video, the presenter demonstrates how to use this feature to improve elements of an existing image, such as enhancing 3D-rendered people or greenery, to achieve a more realistic and photorealistic result.

💡CFG Scale

CFG Scale, or Control Flow Graph Scale, is a parameter in AI models like Stable Diffusion that adjusts the influence of the user's textual prompt on the generated image. Higher CFG scale values make the prompt more dominant, potentially leading to more accurate representation of the prompt but possibly at the expense of image quality. Lower values result in higher quality images but with less adherence to the prompt, introducing more randomness. The video suggests that finding a balance, typically between 4 and 10, is crucial for achieving satisfactory results.
