We are going to first implement this on Windows. “Real” support is dependent on driver support. If on your client machine, the camera app can do it, then this API can also do it. I don’t have a Mac, but there’s platform support<https://bugs.chromium.org/p/chromium/issues/detail?id=1281408>, so we can collaborate once the initial Blink CLs lands.

Thank you for starting this effort! Quick question: Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? Not just exposing backgroundBlur properties but also it "real" support. On Thu, Jun 23, 2022 at 9:26 AM Yoav Weiss <[email protected]<mailto:[email protected]>> wrote: Exciting work!!

Background Blur has become one of the most used features on Video conferencing apps like Teams, Meet, Zoom, Webex, etc. We want give Web apps similar capabilities as their native counterparts, leveraging the same platform APIs and to delight users without completely relying on ML frameworks like TensorFlow.js, Mediapipe, WASM libraries or cloud based solutions. Blink component Blink>ImageCapture<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EImageCapture> Motivation A vast majority of communication these days happens on our client devices. During video meetings, participants are usually aware of how they look and what their environment (usually their home) is revealing to the audience. Most folks, especially ones without a dedicated office space would be inclined to hide messy rooms with pets and kids. Video meetings like face to face meetings are important for non-verbal communication but participants would rather focus on the important subject by removing the distractions in the background and prevent any accidental snafus. Microsoft says<https://www.microsoft.com/en-ww/microsoft-365/business-insights-ideas/resources/how-custom-backgrounds-keep-the-focus-on-you> in a 38 minute conference call, 13 minutes are wasted dealing with distractions and interruptions. Background Blur goes a long way to cutting down those disruptions. Zoom says<https://support.zoom.us/hc/en-us/articles/360061468611-Using-blurred-background>- "When a custom virtual background is unavailable or not suiting your needs, but you still want to maintain some privacy with regards to your surroundings, the blur background option can be a great alternative. This option simply blurs the background of your video, obscuring exactly who or what is behind you. It's great for hiding a cluttered dorm room, taking a meeting in a coffee shop, or just keeping things professional." . In fact, NCSC (National Cyber Security Centre UK) suggests using background Blur or a background image<https://www.ncsc.gov.uk/guidance/video-conferencing-services-security-guidance-organisations> for staff meetings to add a degree of personal privacy. On the Web, due to a lack of a standardized API for Background Blur and widespread demand, developers have no options but to use ML frameworks like Tensorflow.js and other WASM libraries to satisfy their customers. This Background Blur API gives developers a choice to use the native platform's API.
