Abstract
In this paper, we present a novel technique for localization of caption text in video frames based on noise
inconsistencies. Text is artificially added to the video after it has been captured and as such does not form
part of the original video graphics. Typically, the amount of noise level is uniform across the entire
captured video frame, thus, artificially embedding or overlaying text on the video introduces yet another
segment of noise level. Therefore detection of various noise levels in the video frame may signify
availability of overlaid text. Hence we exploited this property by detecting regions with various noise levels
to localize overlaid text in video frames. Experimental results obtained shows a great improvement in line
with overlaid text localization, where we have performed metric measure based on Recall, Precision and fmeasure.
