Abstract

We present a method to locate the caption area of frames in videos. Histogram can be extracted easily from an image, while the color of caption area is apparently brighter than other areas. Unlike previously published methods of using edge detection methods to detect the edge of caption from images, this method uses the caption histogram to detect the caption area, and applies the probabilistic theory to determine the area based on the caption histogram. Experimental results show that our method is practicable and prosperous.
