The core message of this paper is that the domain gap in Heterogeneous Face Recognition (HFR) can be effectively addressed by conceptualizing different modalities as distinct styles and employing a Conditional Adaptive Instance Modulation (CAIM) module to seamlessly adapt the intermediate feature maps of a pre-trained face recognition network.
A novel approach for learning domain-invariant layers called Domain-Invariant Units (DIU) to enhance pretrained face recognition models for the task of heterogeneous face recognition.
