Fast End-to-End Trainable Guided Filter

[Project] [Paper] [arXiv] [Demo] [Home]

Official implementation of Fast End-to-End Trainable Guided Filter.
Faster, Better and Lighter for image processing and dense prediction.

Overview

DeepGuidedFilter is the author's implementation of the deep learning building block for joint upsampling described in:

Fast End-to-End Trainable Guided Filter
Huikai Wu, Shuai Zheng, Junge Zhang, Kaiqi Huang
CVPR 2018

Given a reference image pair in high-resolution and low-resolution, our algorithm generates high-resolution target from the low-resolution input. Through joint training with CNNs, our algorithm achieves the state-of-the-art performance while runs 10-100 times faster.
