Skype has a nice, somewhat hidden function: During video transmissions, you can easily blur the background automatically by clicking on the video button and using the " Blur my background " function. With the help of artificial intelligence, this works with any camera, even without depth information. The whole thing then appears more professional and hides private things in the background or things that are unimportant to the conversation.
To achieve a similar effect in all other programs that use the webcam, tools like CyberLink PerfectCam and XSplit VCam are recommended.
