边缘的

Because of human's head likes an ellipse with longer vertical axis and shorter horizontal axis, we set the position to be a candidate of vertex of minor axis if the vertical projection of vertical edge is high enough in order to speed-up the template matching for ellipse detection.

首先利用Sobel边缘侦测与连续影像相减，再将两者结果交集取出前景物像素；由於头部有类似垂直轴长水平轴短之椭圆的特性，因此将垂直边缘之垂直投影量较高的位置当作椭圆短轴的可能端点，以增进用样板比对做椭圆侦测的效能。
