Pre-trained models

The pre-trained DeFMO model as reported in the paper is available here: https://polybox.ethz.ch/index.php/s/M06QR8jHog9GAcF. Put them into ./saved_models sub-folder.

Inference

For generating video temporal super-resolution:

python run.py --video example/falling_pen.avi

For generating temporal super-resolution of a single frame with the given background:

python run.py --im example/im.png --bgr example/bgr.png

Evaluation

After downloading the pre-trained models and downloading the evaluation datasets, you can run

python eval_dataset.py

Synthetic dataset generation

For the dataset generation, please download:

ShapeNetCore.v2 dataset: https://www.shapenet.org/.
Textures from the DTD dataset: https://www.robots.ox.ac.uk/~vgg/data/dtd/. The exact split used in DeFMO is from the "Neural Voxel Renderer: Learning an Accurate and Controllable Rendering Tool" model and can be downloaded here: https://polybox.ethz.ch/index.php/s/9Abv3QRm0ZgPzhK.
Backgrounds for the training dataset from the VOT dataset: https://www.votchallenge.net/vot2018/dataset.html.
Backgrounds for the testing dataset from the Sports1M dataset: https://cs.stanford.edu/people/karpathy/deepvideo/.
Blender 2.79b with Python enabled.

Then, insert your paths in renderer/settings.py file. To generate the dataset, run in renderer sub-folder:

python run_render.py

Note that the full training dataset with 50 object categories, 1000 objects per category, and 24 timestamps takes up to 1 TB of storage memory. Due to this and also the ShapeNet licence, we cannot make the pre-generated dataset public - please generate it by yourself using the steps above.

Training

Set up all paths in main_settings.py and run

python train.py

Evaluation on real-world datasets

All evaluation datasets can be found at http://cmp.felk.cvut.cz/fmo/. We provide a download_datasets.sh script to download the Falling Objects, the TbD-3D, and the TbD datasets.

Question about training set

Hi, thanks for your generous sharing.

I have a question about training set generating in your work. I generated a training set following your codes. Its size is about 100GB, far less than 1TB. Is there anything wrong?

Thanks.

Apply your model on custom longer video clips

Hi thank you for releasing your code,

Can your model be applied on custom videos about high speed train crossing? Video clips last from 3 to 10 seconds, my idea was to preprocess them with your code in order to keep the same frame rate and have a better video quality for later object detection. This is an example frame from original video clip:

I tried to run your code on a video about 6 seconds and the result was a longer video (about 13min) with a lower level of detail, probably I'm doing something wrong. This is an example frame from output video clip:

How can I correctly reconstruct the quality of single frames usin all the information contained in the video?

Question about comparison with Jin et al.'s work (CVPR2018)

Hi, thank you for your interesting work! I have a question about the comparison of methods in your work. When making comparisons, did you retrain Jin et al.'s model ("Learning to Extract a Video Sequence from a Single Motion-Blurred Image" from CVPR 2018), or did you just use their pre-trained checkpoints? I couldn't find the training code on their github page.

Padding in Time-Consistency Loss

Hi,

Congratulations!

I found that "padding = tuple(side // 10 for side in sh[:2]) + (0,)" for normalized cross-correlation. Does it only implement padding to the height axis, since the padding tuple will be of size (4//10, H//10, 0)?

Thanks a lot.

run on google colab!

I'm confused! and need to run the code on google colab or more explanation about how to implement that code in vscode or something else .if it know someone please help me
