在过去的几年中，已经研究了大量的圆检测方法，用于许多图像处理应用。本文考虑的应用领域是足球比赛。足球图像中的球的识别对于评价进球事件是非常重要的。这个领域是具有挑战性的，因为大量的问题，如闭塞，阴影，物体类似的球，真实的时间处理。这项工作的目的是通过使用一个修改后的版本的方向圆Hough变换获得的实验结果。不同的照明条件已经被考虑，因为它们引入了对图像中球的外观的强烈修改：当图像序列用自然光拍摄时，球看起来像球冠，然后球的搜索已经被修改，以管理这些情况。大量的实验表明，该方法获得了较高的检测分数。
A large number of methods for circle detection has been studied in the last years for numerous image processing applications. The application domain considered in this paper is the soccer game. To identify the ball in soccer images is very important in order to evaluate the goal event. This domain is challenging as a great number of problems has to be managed, such as occlusions, shadows, objects similar to the ball, real time processing. The aim of this work is to present the results of a number of experiments obtained by using a modified version of the directional circle Hough transform. Different lighting conditions have been considered since they introduce strong modifications on the appearance of the ball in the image: when the image sequences are taken with natural light the ball appears as a spherical cap then the search of the ball has been modified in order to manage those situations. A large number of experiments has been carried out showing that the proposed method obtains an high detection score.
