Test

Pretrain models

We provide the test code of our DVC framework. In our imolementation, we use the learning based image compression algorithm (Variational image compression with a scale hyperprior, ICLR'18) as the intra coompression. Specifically, for the video codec model wuth lambda=k, the image codec model with lambda=4k is used as the intra frames. Both the pre-train models of video codec and image codecs in our framework are available at Dropbox.

Entropy Coding

Currently, we do not provide the entropy coding module. The generated features from image/video codecs are saved to .pkl files. We give the estimated Bpp for these features. It is straightforward to compress these features by using traditional entroy coding tools, such as CABAC or Ranger Codec.

Image Compression

cd ./TestDemo/ImageCodec

Image Encoding,

python Encoder.py --EncoderModel /path/to/encoder/model/.pb --input_frame /path/to/image/x.png  --output /output/feature/folder/

Image Decoding,

python Decoder.py --DecoderModel /path/to/decoder/model/.pb   --loadpath  /load/feature/folder/

Video Compression

cd ./TestDemo/VideoCodec

Video Encoding,

python  Encoder.py --EncoderModel /path/to/encoder/model/.pb  --input_frame /path/to/currentframe/im002.png --refer_frame  /path/to/previousframe/im001.png  	--output /output/feature/folder/

Video Decoding,

python Decoder.py --DecoderModel /path/to/decoder/model/.pb  --refer_frame /path/to/previous/im001.png --loadpath  /path/to/feature/folder/

Experimental Results

Evaluation results on the UVG dataset and HEVC Class B (1080p) and Class E (720p). Please refer our paper for more experimental results.

We also provide the scrips for generating all the RD curves of our paper in folder RDCurve.
