    • An estimation device estimates a hidden state of an estimation subject from an observable state in a manner of a time series. The observable state is observed from the hidden state of the estimation subject under a procedure that has a hierarchical structure, which includes the hidden state of the estimation subject, the observable state, and an intermediate hidden state therebetween. The estimation device includes an estimation subject hidden state predicting means, an intermediate hidden state predicting means based on the state transition structure of the hidden state of the estimation subject, an intermediate hidden state likelihood observing means, an intermediate hidden state estimating means, an estimation subject hidden state likelihood observing means, estimation subject hidden state estimating means, an intermediate hidden state predicting means based on the state transition structure of the intermediate hidden state, and the mixing means.

    • A face model providing portion provides an stored average face model to an estimation portion estimating an affine parameter for obtaining a head pose. An individual face model learning portion obtains a result of tracking feature points by the estimation portion and learns an individual face model. The individual face model learning portion terminates the learning when a free energy of the individual face model is over a free energy of the average face model, and switches a face model provided to the estimation portion from the average face model to the individual face model. While learning the individual face mode, an observation matrix is factorized using a reliability matrix showing reliability of each observation value forming the observation matrix with emphasis on the feature point having higher reliability.
    • 面部模型提供部分将估计部分的存储的平均面部模型提供给用于获得头部姿势的仿射参数。 个人面部模型学习部分通过估计部分获得跟踪特征点的结果,并学习个人面部模型。 当个人面部模型的自由能超过平均面部模型的自由能时,个人面部模型学习部分终止学习,并将提供给估计部分的面部模型从平均面部模型切换到个人面部模型。 在学习个人面部模式的同时,使用显示形成观察矩阵的每个观察值的可靠性的可靠度矩阵来分解观察矩阵,强调特征点具有较高的可靠性。
