Abstract (in Japanese) (See Japanese page) 
(in English) Estimating the age of a subject by evaluating brain morphological changes leads diagnostic support
or early detection of disease like Alzheimer’s Disease. In the age estimation method using local features extracted
from T1-weighted MRI images, the accuracy of the age estimation increases when only using effective local features.
By using local features defined by finely divided atlas, estimating accuracy would increase. However, it takes too
much computation time because of the increasing of the number of local regions. To solve this problem, this paper
proposes an efficient method of selecting effective brain local features for age estimation, and evaluate performance
of the proposed method.
