Character localization in video sequences

Character localization in video sequences is considered a complex and diverse problem. This task can be decomposed into two clearly separate problems: localizing the character regions in the source image, and recognizing characters within the regions found. This paper presents a character localization strategy that significantly reduces the computing requirement of this task. First we present the edge detection algorithms considered. Then the results are used to create a histogram of the source image that helps localize character coordinates within the image. Finally, erroneously found regions are discarded using three rapid and effective solutions, featuring very high reliability of the proposed methods.
