摘要:

本文讨论了一种新的面部表情识别系统的方法,该方法从实时网络摄像头的饲料进行面部表情分析在一个接近实时的。主要目标是以接近实时的方式获得具有光不变、人无关和姿态不变的结果。该系统由培训者和评估者两个不同的实体组成。每帧视频都经过一系列步骤,包括haar分类器,皮肤检测,特征提取,特征点跟踪,创建学习的支持向量机模型来分类情感,以实现准确性和结果率之间的权衡。每10帧的处理时间为100-120 ms,精度约为60%。我们根据各种交互和分类场景来衡量我们的准确性。最后,我们讨论我们的工作相关的人机交互,并探讨进一步的措施,可以采取。

英文摘要:

This paper discusses a novel method for Facial Expression Recognition System which performs facial expression analysis in a near real time from a live web cam feed. Primary objectives were to get results in a near real time with light invariant, person independent and pose invariant way. The system is composed of two different entities trainer and evaluator. Each frame of video feed is passed through a series of steps including haar classifiers, skin detection, feature extraction, feature points tracking, creating a learned Support Vector Machine model to classify emotions to achieve a tradeoff between accuracy and result rate. A processing time of 100-120 ms per 10 frames was achieved with accuracy of around 60%. We measure our accuracy in terms of variety of interaction and classification scenarios. We conclude by discussing relevance of our work to human computer interaction and exploring further measures that can be taken.
