Real-Time Measurement of Cycloduction Movement Based on Fast Ellipse Detection

This paper presents it method for real-time cycloduction measurement based oil fast ellipse detection. The Hough transform framework is known to lie effective for ellipse filling, but most of the existing methods have a high computational cost. We therefore present a novel technique for detecting it region of the pupil by fitting an ellipse based on parallelogram. Since our method eliminates Outliers due to lighting, it is possible to obtain the ellipse parameters in high accuracy. Once the ellipse parameter For pupil image is detected, we call generate it projected image of if-is pattern, and then estimate a rotation angle of the cycloduction by SAD matching considering the temporal information. Our experimental results demonstrate the effectiveness and robustness of our method (C) 2009 Wiley Periodicals, Inc.
