Sandwiched Compression: Repurposing Standard Codecs with Neural Network Wrappers

1 code implementation8 Feb 2024 Onur G. Guleryuz, Philip A. Chou, Berivan Isik, Hugues Hoppe, Danhang Tang, Ruofei Du, Jonathan Taylor, Philip Davidson, Sean Fanello

Through a variety of examples, we apply the sandwich architecture to sources with different numbers of channels, higher resolution, higher dynamic range, and perceptual distortion measures.

OmniSyn: Synthesizing 360 Videos with Wide-baseline Panoramas

no code implementations17 Feb 2022 David Li, yinda zhang, Christian Häne, Danhang Tang, Amitabh Varshney, Ruofei Du

Immersive maps such as Google Street View and Bing Streetside provide true-to-life views with a massive collection of panoramas.

Multiresolution Deep Implicit Functions for 3D Shape Representation

no code implementations ICCV 2021 Zhang Chen, yinda zhang, Kyle Genova, Sean Fanello, Sofien Bouaziz, Christian Haene, Ruofei Du, Cem Keskin, Thomas Funkhouser, Danhang Tang

To the best of our knowledge, MDIF is the first deep implicit function model that can at the same time (1) represent different levels of detail and allow progressive decoding; (2) support both encoder-decoder inference and decoder-only latent optimization, and fulfill multiple applications; (3) perform detailed decoder-only shape completion.

HumanGPS: Geodesic PreServing Feature for Dense Human Correspondences

1 code implementation CVPR 2021 Feitong Tan, Danhang Tang, Mingsong Dou, Kaiwen Guo, Rohit Pandey, Cem Keskin, Ruofei Du, Deqing Sun, Sofien Bouaziz, Sean Fanello, Ping Tan, yinda zhang

In this paper, we address the problem of building dense correspondences between human images under arbitrary camera viewpoints and body poses.

A Log-Rectilinear Transformation for Foveated 360-degree Video Streaming

1 code implementation22 Mar 2021 David Li, Ruofei Du, Adharsh Babu, Camelia Brumar, and Amitabh Varshney

With the rapidly increasing resolutions of 360° cameras, head-mounted displays, and live-streaming services, streaming high-resolution panoramic videos over limited-bandwidth networks is becoming a critical challenge.

ORC Layout: Adaptive GUI Layout with OR-Constraints

no code implementations17 Dec 2019 Yue Jiang, Ruofei Du, Christof Lutteroth, Wolfgang Stuerzlinger

We propose a novel approach for constraint-based graphical user interface (GUI) layout based on OR-constraints (ORC) in standard soft/hard linear constraint systems.
