XYDeblur: Divide and Conquer for Single Image Deblurring

CVPR 2022poster

Many convolutional neural networks (CNNs) for single image deblurring employ a U-Net structure to estimate latent sharp images. Having long been proven to be effective in image restoration tasks, a single lane of encoder-decoder architecture overlooks the characteristic of deblurring, where a blurry…

Rethinking Coarse-To-Fine Approach in Single Image Deblurring

ICCV 2021poster

Coarse-to-fine strategies have been extensively used for the architecture design of single image deblurring networks. Conventional methods typically stack sub-networks with multi-scale input images and gradually improve sharpness of images from the bottom sub-network to the top sub-network, yielding…

PEPSI : Fast Image Inpainting With Parallel Decoding Network

CVPR 2019poster

Recently, a generative adversarial network (GAN)-based method employing the coarse-to-fine network with the contextual attention module (CAM) has shown outstanding results in image inpainting. However, this method requires numerous computational resources due to its two-stage process for feature enc…

Parallel Feature Pyramid Network for Object Detection

ECCV 2018poster

Recently developed object detectors employ a convolutional neural network (CNN) by gradually increasing the number of feature layers with a pyramidal shape instead of using a featurized image pyramid. However, the different abstraction levels of the CNN feature layers often limit the detection perfo…
