A Method for Extracting Signboard Regions from Scene Images Using Toggle Mapping

Abstract

In this paper, we propose an approach to extract signboard regions from scene images. We first carry out toggle mapping which is able to detect a region whose intensities are homogeneous. We therefore detect an intensity homogeneous area by using toggle mapping. A support vector machine is applied to classify a homogenous area into signboard or non-signboard classes. Finally, we conduct computer experiments to show the effectiveness for the proposed method.
