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.

该项目将开发一个具有成本效益的图像分析系统 对人脸执行一套全面的测量 录像图像。 该系统将促进情绪研究 以及其他需要客观测量的心理过程 表情。 一个完整的系统将包括消费级 视频录制设备、个人计算机设备以及易于使用的 使用软件。 最终系统中将包括眼睛、眉毛、鼻子、嘴巴和 下巴位置和运动测量，系统最终可以 包括肤色和色调、温度和脉搏波幅度 频率。 该产品的主要优点是：(a) 提供评估全面的面部活动 目前不可用或评估成本太高； (b) 能力 以自然方式非侵入性地记录全方位的措施 设置; (c) 允许研究人员适应系统的灵活性 产出他或她的研究兴趣并创造新的措施； (d) 措施标准化； (e) 成本低。 特征定位和测量技术在 一期将进行完善，并开发新的。 这 将实施完整的制度。 其性能将是 评估以证明系统测量是准确的。
