The aim of this project is to develop a cost-effective video image analysis system, using a standard personal computer, which provides a comprehensive set of measurements from the involves digitizing videotape recordings of the face and automated detection of features system could ultimately include various aspects of facial expression, eye movement, 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 which is either currently unavailable or requires the use of expensive equipment and techniques; (b) an ability to record nonintrusively the full range of measures in naturalistic contexts and laboratory environments; (c) automated measurement of facial movement, relative to current protocols; (d) standardization of measurement techniques, and (e) low cost. Algorithms for feature identification and scoring will be developed and validated Performance will be evaluated to demonstrate that the system can identify landmarks, and differentiate between various facial expressions. In Phase II, the full system will be implemented using inexpensive personal computer and video components.

该项目的目的是开发一种具有成本效益的视频图像分析 系统，使用标准个人计算机，提供全面的 一组测量数据涉及对录像带进行数字化 面部和特征系统的自动检测最终可以 包括面部表情、眼球运动、肤色等各个方面 色调、温度以及脉搏波幅度和频率。 校长 该产品的优点是： (a) 提供评估 全面的面部活动，目前是 不可用或需要使用昂贵的设备和技术； (二) 能够以非侵入方式记录全方位的措施 自然背景和实验室环境； (c) 自动化 相对于当前协议的面部运动测量； (四) 测量技术的标准化，以及(e) 低成本。 将开发特征识别和评分算法 将评估经过验证的性能，以证明系统可以 识别地标，并区分各种面部表情。 在第二阶段，整个系统将使用廉价的个人来实施 计算机和视频组件。
