Character detection in scene images is the process to find characters in scene images. Conventional character detection approaches have utilized features of character shapes. However, there is a limitation on those approaches because the shape and the size of characters have huge variations. In this article, we propose approach which focuses on scene context, such as sky, tree, and buildings. For example, there is rarely any character in sky, and thus by knowing the area of sky in scene images, we can exclude false positives from the area. We confirmed experimentally that precision of the character detection improved by using scene context information.
