Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a guidance method of positions and directions of textured pavement blocks on a cellular phone.
Concerning image processing and navigation, low cost algorithm and easy-to-follow voice guidance are adopted. A hyperplane that discriminates pixels of the blocks and others are determined with Support Vector Machine in advance. On the cellular phone, first, discrimination of pixels in each 3×3-divided region of a photo is carried on using the hyperplane. Then, based on connection patterns of block-existence regions, degenerated navigation patterns for humans are decided. Experimental results with over 90 images show the effectiveness of the proposed method for standard images. It takes about three seconds for image processing.
