Optical character recognition (OCR) of overlaid text in video streams is a challenging problem due to various factors including the presence of dynamic backgrounds, color, and low resolution. In video feeds such as Broadcast News, a particular overlaid text region usually persists for multiple frames during which the background may or may not vary. In this paper we explore two innovative techniques that exploit such multi-frame persistence of videotext. The first technique uses multiple… CONTINUE READING
