Abstract:
Methods and apparatus for detecting moving text in video comprising receiving consecutive frames from a video stream, extracting a sequence of pixels from the consecutive frames, categorizing the pixels, thinning the pixels, correlating corresponding thinned pixels in the frames, identifying the peaks that are equal to or exceed a threshold, and performing further processing on the peaks to determine if the peaks contain moving text.
