Introduction

Our method is a general framework to improve the temporal consistency of video processed by image algorithms. For example, combining image colorization or image dehazing algorithm with our framework, we can achieve the goal of video colorization or video dehazing.

Environment

This code is based on tensorflow. It has been tested on Ubuntu 18.04 LTS.

Anaconda is recommended: Ubuntu 18.04 | Ubuntu 16.04

After installing Anaconda, you can setup the environment simply by

conda env create -f environment.yml
conda activate deep-video-prior

Inference

Demo

bash test.sh

The results are placed in ./result

Use your own data

For the video with unimodal inconsistency:

python dvp_video_consistency.py --input PATH_TO_YOUR_INPUT_FOLDER --processed PATH_TO_YOUR_PROCESSED_FOLDER --task NAME_OF_YOUR_MODEL  --output ./result/OWN_DATA

For the video with multimodal inconsistency:

python dvp_video_consistency.py --input PATH_TO_YOUR_INPUT_FOLDER --processed PATH_TO_YOUR_PROCESSED_FOLDER --task NAME_OF_YOUR_MODEL --with_IRT 1 --IRT_initialization 1 --output ./result/OWN_DATA

Beyond the tasks we evaluated

Researcher found that Blind Temporal Consistency (e.g., DVP) can be applied to many more tasks!

• Video segmentation AuxAdapt: Stable and Efficient Test-Time Adaptation for Temporally Consistent Video Semantic Segmentation
• Video denoising Neural Radiance Flow for 4D View Synthesis and Video Processing
• Low-light Video Enhancement Learning Temporal Consistency for Low Light Video Enhancement from Single Images
