Transparent Text Detection and Background Recovery

Author: Xinhao Liu and Naoki Chiba


We propose two methods for detecting transparent text in images and recovering the background behind the text. Although text detection in natural scenes is an active research area, most current methods are focused on non-transparent text. To detect transparent text, we developed an adaptive edge detection method for edge-based text detection that can accurately detect text even under low contrast, which is common among transparent text images and a method for recovering the original background content behind the detected transparent text. Experiments using real images show the effectiveness of the proposed methods.
