TEXT DETECTION |
摘要 |
In a method of detecting text in a video signal (VS), high horizontal frequencies in the video signal (VS) are detected (ED) to obtain horizontal edge detection results (refo, refpp1, refpp2), and horizontal edge detection results (refo) at a given position are correlated (C) with horizontal edge detection results (refpp1, refpp2) at vertically neighboring positions. |
