First, in image processing, we introduce dilation and erosion, and then evaluate the performance of the guidance blocks shot at outdoor. Second, we evaluate the positioning performance of the warning blocks attaching redundant bits. Last, we introduce the k-means classification on color extraction, and the evaluate the guidance blocks shot at outdoor, the warning blocks shot at indoor/outdoor. As a result, we show possibility of the proposed method in various photographic environments without parameter tuning of the color extraction.","subitem_description_type":"Abstract"}]},"item_116_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"copyright©2014 IEICE","subitem_description_type":"Other"}]},"item_116_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_116_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_116_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"item_116_publisher_12":{"attribute_name":"出版者名（別言語）","attribute_value_mlt":[{"subitem_publisher":"The Institue of Electronics.
