SR VIDEO

This project aims to get a super resolution video version out of a low resolution one. It makes use of the famous H.264 codec as it enhances the I-Frames.

This is WIP and in its early stages.

The implementation is based on "Image Super-Resolution Using Deep Convolutional Networks" paper by "Chao Dong, Chen Change Loy, Kaiming He, Xiaoou Tang "

Dependencies

From apt-get

sudo apt-get install zlib1g zlib1g-dev bzip2 liblzma-dev cmake yasm python3-dev python3-pip python3-wheel python3-numpy libopencv-dev

SDL2

hg clone https://hg.libsdl.org/SDL
cd SDL 
mkdir build && cd build
./configure
make && sudo make install

FFMPEG

Change directory to the repository SuperVideoResolution directory

For CPU version

cd src/libs/ffmpeg
./configure --extra-cflags="-fPIC"  --enable-nonfree --enable-shared  --enable-pic
make

For CUDA compatible vesion

cd src/libs/ffmpeg
./configure --extra-cflags="-fPIC" --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --enable-shared  --enable-pic
make

Tensorflow

For CPU version

wget -L "https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-linux-x86_64-1.12.0.tar.gz"
tar -x -f libtensorflow-cpu-linux-x86_64-1.12.0.tar.gz 

cp lib/libtensorflow.so src/libs/tensorflow/lib/
cp lib/libtensorflow_framework.so src/libs/tensorflow/lib/

cp include/tensorflow/c/c_api.h src/libs/tensorflow/include/tensorflow/c/c_api.h
cp include/tensorflow/c/c_api_experimental.h src/libs/tensorflow/include/tensorflow/c/c_api_experimental.h
cp include/tensorflow/c/eager/c_api.h src/libs/tensorflow/include/tensorflow/c/eager/c_api.h

For CUDA compatible vesion

You have to download tensorflow from the sources and after configuring bazel, do the following

bazel build //tensorflow:libtensorflow.so

cp tensorflow/bazel-bin/tensorflow/libtensorflow.so src/libs/tensorflow/lib/
cp tensorflow/bazel-bin/tensorflow/libtensorflow_framework.so src/libs/tensorflow/lib/

cp tensorflow/tensorflow/c/c_api.h src/libs/tensorflow/include/tensorflow/c/c_api.h
cp tensorflow/tensorflow/c/c_api_experimental.h src/libs/tensorflow/include/tensorflow/c/c_api_experimental.h
cp tensorflow/tensorflow/c/eager/c_api.h src/libs/tensorflow/include/tensorflow/c/eager/c_api.h
