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.
