My team at Google works to make self-expression both more personal and more efficient. One such project was selfie stickers, where a selfie photo is converted into stickers that can be sent to others. This project became available to the public in Allo towards the end of 2017.

User Flow

To use the selfie stickers, users first captured a selfie:

Our project then used machine learning and neural nets to convert the selfie into an Allo sticker pack:

The ML algorithms were quite accurate at converting faces to selfie stickers, but users could also choose to further customize their stickers (face shape, hair, colors, hats, etc.):

Impact

The selfie stickers project was well received by the public:

The Next Web: Google Allo now generates fantastic stickers that look like you

The Verge: Google Allo can now turn your selfies into cartoon stickers

Additionally, the project was highlighted as #1 in Google Design’s Best of 2017.
