AGA-GAN: Attribute Guided Attention Generative Adversarial Network with U-Net for face hallucination

•AGA-GAN uses facial descriptors to generate high-resolution facial images.•Performance increases with additional information about features like facial hair.•Coupling AGA-GAN with UNet gives superior hallucination results.•AGA-GAN and AGA-GAN+UNet, both translate well on downstream face verification tasks.
