要約 Character detection in scenery images is a very difficult task. This paper describes a strategy of selecting character patterns for easier detection in scenery image. These character patterns, called conspicuous character patterns, are selected from character font sets according to a criterion that evaluates how the font has a larger distance from a non-character pattern distribution and, simultaneously, with a smaller distance from a general character pattern distribution. Qualitative and quantitative evaluations have been made to observe how the selected fonts are more conspicuous than other fonts.
