FACIAL SURFACE IMAGING IN BIOBEHAVIORAL ASSESMENT

该项目将开发一个具有成本效益的图像分析系统， 对人脸进行全面的测量， 视频图像。 该系统将促进情感的研究 以及其他需要客观测量的心理过程， 面部表情 一个完整的系统将包括消费级 视频记录设备，个人电脑设备，以及易于- 使用软件。 最终的系统将包括眼睛、眉毛、鼻子、嘴巴和 下巴的位置和运动的措施，该系统最终可以 包括皮肤颜色和色调、温度和脉搏波幅度，且 频率. 该产品的主要优点是：（a） 用于评估全面的面部活动的规定， 目前无法获得或评估费用太高;（B）能力 以非侵入性方式记录自然环境中的各种测量结果， （c）允许研究人员灵活调整系统 输出到他或她的研究兴趣，并创建新的措施; (d)措施标准化;（e）费用低。 特征定位和测量技术的发展， 第一阶段将得到改进，并将开发新的。 的 将建立完整的制度。 它的性能将是 评估以证明系统测量准确。

This project will develop a cost-effective, image analysis system to perform a comprehensive set of measurements of the human face from videotaped images. The system will facilitate the study of emotion and other psychological processes that require objective measures of facial expression. A complete system will consist of consumer-grade video recording equipment, personal computer equipment, and easy-to- use software. Included in the final system will be eye, eyebrow, nose, mouth, and chin position and movement measures, and the system ultimately could include skin color and hue, temperature, and pulse wave amplitude and frequency. The principal advantages of this product will be: (a) provision for assessing a comprehensive range of facial activity that is currently unavailable or too expensive to evaluate; (b) an ability to record nonintrusively a full range of measures in natural settings; (c) flexibility in allowing the researcher to adapt system output to his or her research interests and to create new measures; (d) standardization of measures; and (e) low cost. The techniques for feature location and measurement developed during Phase I will be improved, and new ones will be developed. The complete system will be implemented. Its performance will be evaluated to demonstrate that the system measurements are accurate.
