title = "Fast text caption localization on video using visual rhythm",
abstract = "In this paper, a fast DCT-based algorithm is proposed to efficiently locate text captions embedded on specific areas in a video sequence through visual rhythm, which can be fast constructed by sampling certain portions of a DC image sequence and temporally accumulating the samples along time. Our proposed approach is based on the observations that the text captions carrying important information suitable for indexing often appear on specific areas on video frames, from where sampling strategies are derived for a visual rhythm. Our method then uses a combination of contrast and temporal coherence information on the visual rhythm to detect text frames such that each detected text frame represents consecutive frames containing identical text strings, thus significantly reducing the amount of text frames needed to be examined for text localization from a video sequence. It then utilizes several important properties of text caption to locate the text caption from the detected frames.",
