Extraction of information region on signboard from scene image - the stable background

摘要

In this paper a method using the Stable Background to abstract information from signboard is explained. The ground of signboard is one of the Stable Backgrounds used to perform information, written in signboard, more clearly. We also explained a method to distinguish signboard with other Stable Backgrounds. We extract information from signboard by measuring contrast between color feature of signboard's ground and likely information.
