Direct Voxel Grid Optimization: Super-fast Convergence for Radiance Fields Reconstruction

1 code implementation22 Nov 2021 Cheng Sun, Min Sun, Hwann-Tzong Chen

Finally, evaluation on five inward-facing benchmarks shows that our method matches, if not surpasses, NeRF's quality, yet it only takes about 15 minutes to train from scratch for a new scene.

Flat2Layout: Flat Representation for Estimating Layout of General Room Types

no code implementations29 May 2019 Chi-Wei Hsiao, Cheng Sun, Min Sun, Hwann-Tzong Chen

This paper also constructs a benchmark for validating the performance on general layout topologies, where Flat2Layout achieves good performance on general room types.

A Spatial and Temporal Features Mixture Model with Body Parts for Video-based Person Re-Identification

no code implementations3 Jul 2018 Jie Liu, Cheng Sun, Xiang Xu, Baomin Xu, Shuangyuan Yu

In this paper we propose a novel Spatial and Temporal Features Mixture Model (STFMM) based on convolutional neural network (CNN) and recurrent neural network (RNN), in which the human body is split into $N$ parts in horizontal direction so that we can obtain more specific features.
