Abstract: A simple and effective method is presented for real－time text segmentation and recognition in videos.Firstly，an algorithm is provided which detects text event and gets edges，then makes a size restrict to the edges and eventually wipes off non-text regions according to the textual energy.The overlaying of detected horizontal edges and vertical edges enhances the text edges，the size restrict of edges helps to wipe off the non-text edges.Later，image projection is applied to get text regions.Eventually，the text regions are processed by OCR technology.The combination of these methods guarantees the performance of this algorithm.
