Frequency Reflection Modulation for Reconfigurable Intelligent Surface Aided OFDM Systems

no code implementations19 Apr 2021 Wenjing Yan, Xiaojun Yuan, Xuanyu Cao

Reconfigurable intelligent surface (RIS) based reflection modulation has been considered as a promising information delivery mechanism, and has the potential to realize passive information transfer of a RIS without consuming any additional radio frequency chain and time/frequency/energy resources.

RAF-AU Database: In-the-Wild Facial Expressions with Subjective Emotion Judgement and Objective AU Annotations

no code implementations12 Aug 2020 Wenjing Yan, Shan Li, Chengtao Que, JiQuan Pei, Weihong Deng

Much of the work on automatic facial expression recognition relies on databases containing a certain number of emotion classes and their exaggerated facial configurations (generally six prototypical facial expressions), based on Ekman's Basic Emotion Theory.
