Abstract:
1. An image processor, which outputs a result of an estimation of a hidden state of an estimation subject from an observable state in an image in a manner of a time series, wherein: the observable state is observed from the hidden state of the estimation subject under a procedure that has a hierarchical structure, wherein: the hierarchical structure includes: in the hierarchical structure: the image processor comprises: means for producing predictive information of the hidden state of the estimation subject including an accuracy reduction due to disturbance at a present time t, using: means for producing predictive information of the intermediate hidden state based on the state transition structure of the hidden state of the estimation subject including the accuracy reduction due to the disturbance at the present time t, using: means for producing likelihood of the intermediate hidden state including an accuracy reduction due to disturbance at the present time t, using: means for processing the predictive information; means for producing estimative information of the intermediate hidden state at the present time t, using: means for producing likelihood of the hidden state of the estimation subject at the present time t, using: means for producing the estimative information of the hidden state of the estimation subject at the present time t, using: means for producing predictive information of the intermediate hidden state based on the state transition structure of the intermediate hidden state including the accuracy reduction due to the disturbance at the present time t, using:
