要約
In this paper, design and recognition of human-readable
and machine-readable patterns are investigated. Specifically
speaking, we design character images printed with a
horizontal stripe pattern, called a cross ratio pattern. The
cross ratio derived from the cross ratio pattern represents
the class information of the character. Since the cross ratio
is invariant to projective distortion, the class information is
extracted correctly regardless of camera angle. The character
image itself is human-readable and therefore the character
image with the cross ratio pattern is not only humanreadable
and but also machine-readable and can be used as
a medium for human-machine communication.
