Blind Image Super Resolution with Semantic-Aware Quantized Texture Prior

1 code implementation26 Feb 2022 Chaofeng Chen, Xinyu Shi, Yipeng Qin, Xiaoming Li, Xiaoguang Han, Tao Yang, Shihui Guo

Since features in the codebook have shown the ability to generate natural textures in the pretrain stage, QuanTexSR can generate rich and realistic textures with the pretrained codebook as texture priors.

A Unified Framework for Masked and Mask-Free Face Recognition via Feature Rectification

1 code implementation15 Feb 2022 Shaozhe Hao, Chaofeng Chen, Zhenfang Chen, Kwan-Yee K. Wong

We introduce rectification blocks to rectify features extracted by a state-of-the-art recognition model, in both spatial and channel dimensions, to minimize the distance between a masked face and its mask-free counterpart in the rectified feature space.

Learning Spatial Attention for Face Super-Resolution

1 code implementation2 Dec 2020 Chaofeng Chen, Dihong Gong, Hao Wang, Zhifeng Li, Kwan-Yee K. Wong

Visualization of the attention maps shows that our spatial attention network can capture the key face structures well even for very low resolution faces (e. g., $16\times16$).

Progressive Semantic-Aware Style Transformation for Blind Face Restoration

1 code implementation CVPR 2021 Chaofeng Chen, Xiaoming Li, Lingbo Yang, Xianhui Lin, Lei Zhang, Kwan-Yee K. Wong

Compared with previous networks, the proposed PSFR-GAN makes full use of the semantic (parsing maps) and pixel (LQ images) space information from different scales of input pairs.

Face Sketch Synthesis with Style Transfer using Pyramid Column Feature

1 code implementation18 Sep 2020 Chaofeng Chen, Xiao Tan, Kwan-Yee K. Wong

We utilize a fully convolutional neural network (FCNN) to create the content image, and propose a style transfer approach to introduce textures and shadings based on a newly proposed pyramid column feature.

Blind Face Restoration via Deep Multi-scale Component Dictionaries

1 code implementation ECCV 2020 Xiaoming Li, Chaofeng Chen, Shangchen Zhou, Xianhui Lin, WangMeng Zuo, Lei Zhang

Next, with the degraded input, we match and select the most similar component features from their corresponding dictionaries and transfer the high-quality details to the input via the proposed dictionary feature transfer (DFT) block.

SAFE: Scale Aware Feature Encoder for Scene Text Recognition

no code implementations17 Jan 2019 Wei Liu, Chaofeng Chen, Kwan-Yee K. Wong

We propose a novel scale aware feature encoder (SAFE) that is designed specifically for encoding characters with different scales.

Semi-Supervised Learning for Face Sketch Synthesis in the Wild

1 code implementation12 Dec 2018 Chaofeng Chen, Wei Liu, Xiao Tan, Kwan-Yee K. Wong

Instead of supervising the network with ground truth sketches, we first perform patch matching in feature space between the input photo and photos in a small reference set of photo-sketch pairs.

Char-Net: A Character-Aware Neural Network for Distorted Scene Text Recognition

no code implementations AAAI 2018 Wei Liu, Chaofeng Chen, Kwan-Yee K. Wong

Unlike previous work which employed a global spatial transformer network to rectify the entire distorted text image, we take an approach of detecting and rectifying individual characters.
