Wavelet-SRNet: A Wavelet-Based CNN for Multi-scale Face Super Resolution

Abstract

Most modern face super-resolution methods resort to convolutional neural networks (CNN) to infer highresolution (HR) face images. When dealing with very low resolution (LR) images, the performance of these CNN based methods greatly degrades. Meanwhile, these methods tend to produce over-smoothed outputs and miss some textural details. To address these… (More)
