cd SRN-DeblurDownload pretrained models through: download_model.sh inside checkpoints/.
To test blur images in a folder, just use arguments
--input_path= and save the outputs to --output_path=.
For example:
python run_model.py --input_path=./testing_set --output_path=./testing_resIf you have a GPU, please include --gpu argument, and add your gpu id to your command.
Otherwise, use --gpu=-1 for CPU.
python run_model.py --gpu=0To test the model, pre-defined height and width of tensorflow
placeholder should be assigned.
Our network requires the height and width be multiples of 16.
When the gpu memory is enough, the height and width could be assigned to
the maximum to accommodate all the images.
Otherwise, the images will be downsampled by the largest scale factor to be fed into the placeholder. And results will be upsampled to the original size.
According to our experience, --height=720 and --width=1280 work well
on a Gefore GTX 1050 TI with 4GB memory. For example,
python run_model.py --height=720 --width=1280The quantitative results of PSNR and SSIM in the paper is
calculated using MATLAB built-in function psnr() and ssim() based
on the generated color results.
We trained our model using the dataset from
DeepDeblur_release.
Please put the dataset into training_set/. And the provided datalist_gopro.txt
can be used to train the model.
Hyper parameters such as batch size, learning rate, epoch number can be tuned through command line:
python run_model.py --phase=train --batch=16 --lr=1e-4 --epoch=4000We provided 3 models (training settings) for testing:
--model=lstm: This model implements exactly the same structure in our paper.
Current released model weights should produce PSNR=30.19, SSIM=0.9334 on GOPRO testing dataset.--model=gray: According to our further experiments after paper acceptance, we are able
to get a slightly better model by tuning parameters, even without LSTM.
This model should produce visually sharper and quantitatively better results. --model=color: Previous models are trained on gray images, and may produce color
ringing artifacts. So we train a model directly based on RGB images.
This model keeps better color consistency, but the results are less sharp.If you would like to compare performance against our method, you can use
model gray and lstm.
If you want to restore blurry images you can try gray and color.
And color is very useful in low-light noisy images.
