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 pixel-wise image prediction.

Overview

DeepGuidedFilter is the author's implementation of:

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

With our method, FCNs can run 10-100 times faster w/o performance drop.

   pip install -r requirements.txt

Ready to GO !

Image Processing

cd ImageProcessing/DeepGuidedFilteringNetwork

python predict.py  --task auto_ps \
                   --img_path ../../images/auto_ps.jpg \
                   --save_folder . \
                   --model deep_guided_filter_advanced \
                   --low_size 64 \
                   --gpu 0

See Here or python predict.py -h for more details.

Semantic Segmentation with Deeplab-Resnet

1. Enter the directory.

   cd ComputerVision/Deeplab-Resnet

2. Download the pretrained model [Google Drive|BaiduYunPan].
3. Run it now !

   python predict_dgf.py --img_path ../../images/segmentation.jpg --snapshots [MODEL_PATH]

Note:

1. Result is in ../../images.
2. Run python predict_dgf.py -h for more details.

Saliency Detection with DSS

1. Enter the directory.

   cd ComputerVision/Saliency_DSS

2. Download the pretrained model [Google Drive|BaiduYunPan].
3. Try it now !

   python predict.py --im_path ../../images/saliency.jpg \
                     --netG [MODEL_PATH] \
                     --thres 161 \
                     --dgf --nn_dgf \
                     --post_sigmoid --cuda

Note:

1. Result is in ../../images.
2. See Here or python predict.py -h for more details.

Monocular Depth Estimation

1. Enter the directory.

   cd ComputerVision/MonoDepth

2. Download and Unzip Pretrained Model [Google Drive|BaiduYunPan]
3. Run on an Image

   python monodepth_simple.py --image_path ../../images/depth.jpg --checkpoint_path [MODEL_PATH] --guided_filter

Note:

1. Result is in ../../images.
2. See Here or python monodepth_simple.py -h for more details.
