亚椭圆算子

A new method was given for determining the eye movement in a video-oculography system, where the centroid method was used to get the initial position of eye center, a edge filter was used to obtain all the boundary of the pupil, then a ellipse fatting was used to determine the accurate position of the eye center.

本文提出了一种全自动确定眼动平动的新方法。首先用形心法确定瞳孔的初始位置，再用亚像素边界算子提取瞳孔边界，并用带自动优化功能的椭圆拟合最终确定瞳孔的精确位置。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
