Understanding How Zoom's AI Creates Blurred Backgrounds

Zoom's artificial intelligence (AI) capabilities have enhanced the platform's usability and versatility, particularly when it comes to blurring backgrounds.

Zoom and Artificial Intelligence:

Zoom uses AI to identify and distinguish between the participant (foreground) and their environment (background). The AI is responsible for creating a real-time mask over the user in the video, which remains consistent, even as the user moves. This dynamic identification process enables Zoom to blur the background while keeping the user in focus.

Role of Machine Learning:

Underlying the AI feature is machine learning. Zoom's machine learning algorithms have been trained with numerous images and video sequences to understand what constitutes a human subject versus a background in a video frame. As the algorithms continue to be exposed to more data over time, their accuracy at separating foreground and background improves, enhancing the effectiveness of the blur feature.

Tips for Improving the Quality of the Blurred Background

To achieve the best possible blurred background in your Zoom calls, consider the following:

Your Position Within the Frame:

Ensure you are centered in the camera frame and maintain some distance from the background. This physical separation helps Zoom's AI differentiate between you and the background, creating a more effective blur.

Using Proper Lighting:

Good lighting is key to improving the blur quality. Aim for a well-lit room with a light source in front of you. Backlighting can confuse the AI and result in an inconsistent blur effect.

Choosing the Right Clothes:

Avoid clothing that closely matches your background color. This can make it hard for Zoom's AI to distinguish between you and the background. Opt for colors that contrast with your surroundings for the best blur effect.

How to Blur Your Background During Ongoing Zoom Meetings

It's possible to change your Zoom background even during an ongoing meeting.

Steps to Blur the Background During an Ongoing Meeting:

1. While in the meeting, move your cursor to the bottom of the screen to display the meeting controls.
2. Click on the '^' arrow next to the 'Stop Video' button.
3. Select 'Choose Virtual Background...'
4. In the settings window, choose the 'Blur' option.
   

Switching Between Blurred and Clear Backgrounds:

To switch between a blurred background and a clear one during a meeting, you can follow the steps above but select 'None' instead of 'Blur' under the 'Choose Virtual Background...' option. This will remove the blur and show your real background.
