Learning Neural Volumetric Field for Point Cloud Geometry Compression

1 code implementation11 Dec 2022 Yueyu Hu, Yao Wang

The neural field representation of the point cloud includes the network parameters and all the latent codes, which are generated by using back-propagation over the network parameters and its input.

Learning to Predict on Octree for Scalable Point Cloud Geometry Coding

no code implementations6 Sep 2022 Yixiang Mao, Yueyu Hu, Yao Wang

Octree-based point cloud representation and compression have been adopted by the MPEG G-PCC standard.

Neural Data-Dependent Transform for Learned Image Compression

1 code implementation CVPR 2022 Dezhao Wang, Wenhan Yang, Yueyu Hu, Jiaying Liu

Learned image compression has achieved great success due to its excellent modeling capacity, but seldom further considers the Rate-Distortion Optimization (RDO) of each input image.

Towards Low Light Enhancement with RAW Images

no code implementations28 Dec 2021 Haofeng Huang, Wenhan Yang, Yueyu Hu, Jiaying Liu, Ling-Yu Duan

In this paper, we make the first benchmark effort to elaborate on the superiority of using RAW images in the low light enhancement and develop a novel alternative route to utilize RAW images in a more flexible and practical way.

Video Coding for Machine: Compact Visual Representation Compression for Intelligent Collaborative Analytics

no code implementations18 Oct 2021 Wenhan Yang, Haofeng Huang, Yueyu Hu, Ling-Yu Duan, Jiaying Liu

By keeping in mind the transferability among different machine vision tasks (e. g. high-level semantic and mid-level geometry-related), we aim to support multiple tasks jointly at low bit rates.

Progressive Spatial Recurrent Neural Network for Intra Prediction

2 code implementations6 Jul 2018 Yueyu Hu, Wenhan Yang, Mading Li, Jiaying Liu

With preceding pixels as the context, traditional intra prediction schemes generate linear predictions based on several predefined directions (i. e. modes) for blocks to be encoded.

A Group Variational Transformation Neural Network for Fractional Interpolation of Video Coding

no code implementations19 Jun 2018 Sifeng Xia, Wenhan Yang, Yueyu Hu, Siwei Ma, Jiaying Liu

Then a group variational transformation technique is used to transform a group of copied shared feature maps to samples at different sub-pixel positions.
