In this paper, a new text extraction method is proposed for digital video. The text in the video frames is extracted by means of the independent component analysis (lCA). Two representations of the image frames are introduced to fit the need of the ICA procedure. The font, color, scale, and orientation of the subtitles in the sample videos are changed to evaluate the performance of our method. We use the gray values as the features. The experimental results show that the method we developed in this research can extract the texts in digital video more efficiently and accurately than the conventional work, without any influence on the variations of font, color, scale, and orientation of texts.
