Abstract

There has been an increase in the number of images on the Internet that contain private information and/or the URL of an illegal Web site. This information could result in a violation of human rights and/or a crime. We present a method for extracting from an image the region(s) that contain characters. Our method uses the discrete wavelet transform and the empirical knowledge that characters have strong vertical and/or horizontal elements. The experimental results show the usefulness of our method.
