On the basis of difference edge mask and current edge mask, a binary edge model of the video object is initialized.

其次在相邻帧差分边缘和当前帧边缘的基础上，检测出视频对象的初始边缘模板。

Once they hit the edge of a cone, drops are propelled towards its base, the least curved region, because of the pressure difference caused by surface tension.

一旦水滴流到了圆锥体的边缘，就会在锥体表面张力所形成的压力差的作用下流向它的底座，那里是曲线弧度最小的地方。

For example, an edge might be a contrast between values (the difference between light and dark), colors, textures, or even rhythms (repetition of imagery), without the use of line at all.

例如，边可能是属性值(明暗差异)、颜色、纹理乃至规律(图像反复)的对比，完全与线无关。
