Simple Frame Marker for Image and Character Recognition

In this paper, we propose Simple Frame Marker (SFM) which has a rectangular frame and encompasses a planar natural view such as characters, logos and images. In order to support recognition of characters as well as an image, Simple Frame Marker is constructed by square-type and rectangle-type markers. Therefore Simple Frame Marker first distinguishes its content by the marker type and applies a proper recognition method for the content. We describe how to construct Simple Frame Marker and how to discriminate different types of Simple Frame Marker.
