Current character extraction systems for scene images are not robust for most real-world applications. In contrast, the system present here achieves robust performance by using morphological segmentation. This paper describes a new morphological segmentation algorithm-differential top-hats (DTT). In, addition, a complete system for extraction of characters from color scene images is presented. The system was verified through experiments on sequences of outdoor color images with varying external conditions. A high average extraction rate of 95% is obtained
