| Abstract(in English) | This paper proposes a method for Eigenspace-based prediction of a person's path in future with current path. This method uses BPLP proposed by Amano et. al.: projection and backprojection of the current path onto Eigenspace. However, the prediction does not take the nature of a path of pedestrian and results in non-smooth path. The proposed method modify the prediction by using null vectors in the orthocomplement of the learned Eigenspace and adding linear combinations of the null vectors to the prediction so that the path becomes smooth. Coefficients of the linear combinations are computed by decent gradient method. Some experimental results on actual pathes are shown. |
