Description: 这是一篇关于椭圆检测的文章:对于做人脸识别,模式识别的同行应该会有所帮助.找了好久,才下到,上传来共享下.-abstract:The Hough transformation can detect straight lines in an edge-enhanced picture, however its extension torecover ellipses
requires too long a computing time. This correspondence proposes a
modified method which utilizes two properties of an ellipse in such a
way that it iteratively searches for clusters in two different parameter
spaces to find almost complete ellipses, then evaluates their parameters
by the least mean squares method.

Description: 改进HOUGH变换在虹膜定位中的应用研究
提出了一种基于改进Hough变换(HT)的虹膜定位算法，解决标准HT定位虹膜计算量较大，且定位不准确的问题．方法根据虹膜的形状和圆近似的性质，用改进的圆HT定位虹膜。定位时采用点对和梯度信息确定潜在的虹膜中心和对应的圆半径．为了使输出结果仅为虹膜的外边界，定义了一个阂值．结果采用点对和梯度信息并定义相应的闪值定位虹膜，在较大程度上减少了计算量，并且保证输出结果为虹膜的外边界．结论采用改进HT能以较小的计算代价准确地定位虹膜．-Improved HOUGH transform the iris Positioning study proposes an approach based on improved Hough transform (HT) iris location algorithm to solve the standard HT locate iris large amount of calculation, and the positioning is not accurate. Methods based on the shape of the iris and the approximate nature of the circle, using a modified round HT positioning iris. Positioning using point and gradient information to determine the potential of the iris center and the radius of the circle corresponds. In order to make the output of only the outer boundary of the iris, the definition of a thresholding. Results using point and gradient information, and define the appropriate value of the location of the flash iris, to a significant extent, reduce the amount of computation, and to ensure output of the outer boundary of the iris. Conclusion The improved HT smaller computational cost can accurately locate the iris.
