Description

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 might result in a violation of human rights and/or a crime. Based on a previously proposed method, we propose a method for judging whether characters have been inserted into an image using the discrete wavelet transform, the image compression characteristics, and the empirical knowledge that characters have strong vertical and/or horizontal elements.
