"The kiss detection model used by Photobooth is a variation of the Image Content Model (ICM) trained for Google Clips, fine-tuned specifically to focus on kissing. The ability to identify people kissing on the camera is the USP, though. To enable the great experience automatically, Google has worked with photographers that help the new system identify five key expressions, namely smiles, tongue-out, kissy/ duck face, puffy-cheeks, and surprise. Google claims that the mode automatically captures photos when the camera is steady and subjects in the frame are seen to have good expressions with their eyes open.

Sitting alongside the existing Top Shot and Portrait modes, the Photobooth mode on Pixel 3 is aimed to capture your "best pictures possible" using artificial intelligence (AI) based algorithms. The development is initially limited to the default Camera app available on the Pixel 3 models. However, apart from capturing couples when they kiss, the new mode on Pixel 3 phones can help users capture their solo and group selfies with expressions such as smile, tongue-out, duck face, and surprise. Google says that the Photobooth relies on two distinct models to capture kissing scenes - a model for facial expressions and another model to detect when people kiss. The shutter-free mode that is inspired by the automatic photography of Google Clips is specially programmed to detect kissing. Google Pixel 3 range has got the all-new Photobooth mode that is designed to capture selfies automatically, with triggers like kissing, smiling, and more.
