| Abstract(in English) | We propose a model that recognizes alphabet characters for various size and rotational position. Normalization using Hough transformation is introduced as preprocess. Center of characters is set to center (ρ=0) at Hough plain and size of characters are regulated by normalization of ρ-direction of their Hough images. In order to treat all rotational changes, Hough transformed image of characters are divided at ρ=0 axis and arranged along θ-axis. Normalizations of arbitrary angles is realized by them. According to this, we showed that it could recognize alphabets and handwriting characters by simulation. |
