这篇文章，提出了一种可以精确检测椭圆特征参数的线性算子。基于双曲线模型，该算子直接检测椭圆边界附近的原始梯度信息，这样可以避免中间精确提取椭圆边缘点的过程。当计算最小代数距离时，双曲线可以受双椭圆约束。这种算法将与其他算法确定中心位置方面进行比较，我们也将通过实际实验来比较。-This article presents a precise detection of the characteristic parameters of the linear elliptic operator. Based on the hyperbolic model, the direct measurement of the elliptic operator near the border of the original gradient information, this can be avoided between precision elliptical edge point extraction process. When calculating the minimum distance algebra, the hyperbola can be bound by the dual-oval. This algorithm will work with other algorithms to identify aspects of the center, we will also be adopted to compare the actual experiment.
