| Abstract(in English) | Deformations in handwritten characters can be considered to have their peculiar directions. For example, handwritten characters of class "A" are often deformed by global slant transformation, whereas they are not deformed to be similar to "R". In this paper, the extraction of such peculiar deformation directions called eigen-deformations are investigated. The key idea is the principal component analysis of a set of deformations collected automatically by elastic matching. From experimental results, it was shown that the typical deformations of each character class were extracted as eigen-deformations. In addition, it was also experimentally shown that the those eigen-deformations are useful to improve the performance of an elastic matching-based recognition system by suppressing overdeformation. |
