Text detection for video analysis
Lalitha Agnihotri, Nevenka Dimitrova · 2003
Textual information brings important semantic clues in video content analysis. We describe a method for detection and representation of text in video segments. The method consists of seven steps: channel separation, image enhancement, edge detection, edge filtering, character detection, text box detection, and text line detection. Our results show that this method can be applied to English as well as non-English text (such as Korean) with precision and recall of 85%.
