中文摘要：
针对渐变的特点，提出了一种基于非相邻帧差的通用渐变镜头检测方法，该方法利用非相邻帧差有效地突出了渐变的特征，利用窗口最大值准确地找到渐变的中心位置，该方法不用设置全局阂值，与具体的渐变转换效果无关，适应性强。实验表明该算法取得了恿好的检测效果。
英文摘要：
According to the characters of gradual change, a generic boundary detection method is proposed. The characters of gradual change is revealed by non-neighbor frame difference and the center position of gradual change is discovered by windowdifference maximum. This method doesn＇ t need to consider global threshold and has no relation to the special gradual transition effects. So it has strongly adaptability to various gradual change shots. Experiments show that our method performs better results,
