Seminar in Faculty of Computing at Rabigh about "An Advanced Method of Overlay Text Detection, Extraction, Removal Using Transition Map and Inpaint"


Mr. Shajhan presented a seminar about "An Advanced Method of Overlay Text Detection, Extraction, Removal Using Transition Map and Inpaint" in Faculty of Computing and Information Technology at Rabigh on Monday 28/3/2011 at 12:00 noon.
The brief of the seminar as follows:

Overlay text brings important semantic clues in video content analysis such as video information retrieval and summarization, since the content of the scene or the editor’s intention can be well represented by using inserted text. Overlay text extraction for video optical character recognition (OCR) becomes more challenging, compared to the text extraction for OCR tasks of document images, due to the numerous difficulties resulting from complex background, unknown text color, size and so on. This proposed system solves the overlay text detection, OCR process and overlay removal. For overlay text detection the transition map is used. For OCR process font matching method is used. The overlay-removal is handled by Hybrid inpaint method which is the combination of sub-patch method and weighted interpolation method. Using this proposed method one can get the marked overlay texts, list of unique overlay texts and Overlay text removed videos. This method produces better than the previous methods. Resultant accuracy is highly improved.
