Mixed-Resolution Image Representation and Compression with Convolutional Neural Networks

no code implementations2 Feb 2018 Lijun Zhao, Huihui Bai, Feng Li, Anhong Wang, Yao Zhao

Firstly, given one input image, feature description neural network (FDNN) is used to generate a new representation of this image, so that this image representation can be more efficiently compressed by standard codec, as compared to the input image.

Learning a Virtual Codec Based on Deep Convolutional Neural Network to Compress Image

1 code implementation16 Dec 2017 Lijun Zhao, Huihui Bai, Anhong Wang, Yao Zhao

Due to the challenge of directly learning a non-linear function for a standard codec based on convolutional neural network, we propose to learn a virtual codec neural network to approximate the projection from the valid description image to the post-processed compressed image, so that the gradient could be efficiently back-propagated from the post-processing neural network to the feature description neural network during training.
