Abstract：Ellipse Hough transform method is a significant research topic in the field of feature extraction. Efficient Hough transform (EHT) is proposed to improve the algorithm's accuracy and timeliness. This method is suitable for detecting the ellipse contour in cylindrical feature. The algorithm mainly consists of estimating other parameters' approximation by single parameter's approximation. EHT's failure model is proposed to give the security error range of preset parameter. Synthetic images of ellipse contour are tested to demonstrate EHT's effectiveness.
