Abstract  

The super-resolution(SR) of high magnification single face image is a hard but valuable task. In the face super-resolution(FSR) task, the end-to-end network SR image is fuzzy, and the photoreality and human visual effect are poor. Aiming at the problems, a FSR algorithm based on multi-task adversarial learning(MTAL) and antinoise adversarial learning(ANAL) is proposed. The algorithm is divided into end-to-end network learning and network parameters fine-tuning. To improve the end-to-end learning result, a deep multi-task Laplacian pyramid network(MTLapNet) is designed and integrated with MTAL. The main task is end-to-end learning, while the subtask is the optimization of adversarial learning penalty function. To improve the result of adversarial learning and parameters fine-tuning of the main task network, ANAL is integrated into the optimization process of discriminator of adversarial learning. The experiments show that the proposed algorithm can make the FSR image more photo-realistic and more consistent with human visual habits.
