AdaDeId: Adjust Your Identity Attribute Freely

Face de-identification has drawn increasing attention in recent years. It is important to protect people’s identity information meanwhile keeping the utility of the face data in many computer vision tasks. We propose a Adaptive De-identification (AdaDeId) method, a novel approach that can freely manipulate the identity attributes of given faces. We introduce an identity decoupling representation learning method, which is based on the autoencoder decoupling model as well as our proposed Identity Decoupling Representation (IDR) loss and Content Retention (CR) loss. Our method encodes the identity information of a face into a unit spherical space, where we can continuously manipulate the identity representation vector. Various de-identified faces derived from an original face can be generated through our method and maintain high similarity to the original image contents. Quantitative and qualitative experiments demonstrate our method achieves state-of-the-art on visual quality and de-identification validity.
