Two-step registration in 3D human body scanning based on multiple RGB-D sensors

no code implementations1 Dec 2015 Pengpeng Hu, Yueqi Zhong, Ge Wu, Duan Li

In this paper, we propose a universal registration method for the body scanner consists of multiple fixed sensors.

Automatic body measurement based on slicing loops

no code implementations4 Jun 2016 Yueqi Zhong, Duan Li, Ge Wu, Pengpeng Hu

The purpose of this paper is to propose a new method of body measurement based on the loop structure.

Automatic foot scanning and measurement based on multiple RGB-depth cameras

no code implementations25 Nov 2016 Ge Wu, Duan Li, Pengpeng Hu, Yueqi Zhong, Ning Pan

In this paper, a system with six depth cameras was built to scan both feet simultaneously.

A study on improving the calibration of body scanner built on multiple RGB-Depth cameras

no code implementations5 Jun 2017 Ge Wu, Duan Li, Yueqi Zhong, Pengpeng Hu

Purpose The calibration is a key but cumbersome process for 3D body scanning using multiple depth cameras.

3D textile reconstruction based on KinectFusion and synthesized texture

no code implementations6 Nov 2017 Pengpeng Hu, Taku Komura, Duan Li, Ge Wu, Yueqi Zhong

Purpose The purpose of this paper is to present a novel framework of reconstructing the 3D textile model with synthesized texture.

Foot shape prediction using elliptical Fourier analysis

no code implementations17 Dec 2017 Ge Wu, Duan Li, Pengpeng Hu, Yueqi Zhong, Ning Pan

In this paper, a new method was proposed to establish the relationship between three-dimensional (3D) foot shapes and their two-dimensional (2D) foot silhouettes, through which a complete 3D foot shape can be predicted by simply inputting its two 2D silhouettes.

Personalized 3D mannequin reconstruction based on 3D scanning

no code implementations16 Apr 2018 Pengpeng Hu, Duan Li, Ge Wu, Taku Komura, Dongliang Zhang, Yueqi Zhong

A personalized mannequin is essential for apparel customization using CAD technologies.

Automatic three-dimensional-scanned garment fitting based on virtual tailoring and geometric sewing

no code implementations19 Dec 2018 Duan Li, Yueqi Zhong, Ge Wu, Pengpeng Hu

The patches of the three-dimensional garment were automatically positioned around the human model by setting up the correspondence via feature matching.

Revised Progressive-Hedging-Algorithm Based Two-layer Solution Scheme for Bayesian Reinforcement Learning

no code implementations21 Jun 2019 Xin Huang, Duan Li, Daniel Zhuoyu Long

Stochastic control with both inherent random system noise and lack of knowledge on system parameters constitutes the core and fundamental topic in reinforcement learning (RL), especially under non-episodic situations where online learning is much more demanding.

BERT-based Financial Sentiment Index and LSTM-based Stock Return Predictability

no code implementations21 Jun 2019 Joshua Zoen Git Hiew, Xin Huang, Hao Mou, Duan Li, Qi Wu, Yabo Xu

On the other hand, by combining with the other two commonly-used methods when it comes to building the sentiment index in the financial literature, i. e., the option-implied and the market-implied approaches, we propose a more general and comprehensive framework for the financial sentiment analysis, and further provide convincing outcomes for the predictability of individual stock return by combining LSTM (with a feature of a nonlinear mapping).

Scenario-decomposition Solution Framework for Nonseparable Stochastic Control Problems

no code implementations18 Oct 2020 Xin Huang, Duan Li, Daniel Zhuoyu Long

When stochastic control problems do not possess separability and/or monotonicity, the dynamic programming pioneered by Bellman in 1950s fails to work as a time-decomposition solution method.

Tackling A Class of Hard Subset-Sum Problems: Integration of Lattice Attacks with Disaggregation Techniques

no code implementations18 Feb 2022 Bojun Lu, Duan Li, Rujun Jiang

Subset-sum problems belong to the NP class and play an important role in both complexity theory and knapsack-based cryptosystems, which have been proved in the literature to become hardest when the so-called density approaches one.

Integrating Different Informations for Portfolio Selection

no code implementations29 May 2023 Yi Huang, Wei Zhu, Duan Li, Shushang Zhu, Shikun Wang

Following the idea of Bayesian learning via Gaussian mixture model, we organically combine the backward-looking information contained in the historical data and the forward-looking information implied by the market portfolio, which is affected by heterogeneous expectations and noisy trading behavior.
