# Virtual Background Generation

### Virtual Background Generation

Zoom’s Generative AI Virtual Background feature allows users to create custom AI-generated backgrounds for their meetings without the need for manual image selection or uploads. By leveraging generative AI, users can quickly generate unique and professional virtual backgrounds tailored to their preferences, enhancing their on-screen presence with minimal effort. Users simply input text, which is transformed into an image output through Zoom’s fine-tuned, internally-hosted model.

When AI Companion processes the user's input, the algorithm converts the request into patterns—called embeddings—that correspond to elements of the request. These embeddings convert the meaning of words into the mathematical format that the algorithm uses to generate images, essentially turning human language into machine-readable instructions for creating visual content. After, the system then introduces "noise" to the canvas, which establishes a baseline for the image.

The Stable Diffusion model then begins its iterative refinement process, gradually removing the noise while using the text embeddings as guidance. Through multiple steps, the algorithm transforms the random static into recognizable features, with each iteration bringing the image closer to matching the original request. This step-by-step denoising approach allows AI Companion to create images by making small, controlled improvements at each stage until the final visual output emerges.

Before delivering the image to the user, the system processes it through a third-party moderation service, which analyzes the generated content to help avoid offensive images, then the image is returned back to the user’s Zoom Workplace app.
