提出了一种识别圆的两步算法。第一步使用2D Hough变换来检测圆的中心，第二步通过半径组织图来验证它们的存在。2D Hough变换技术利用了圆的每一根弦都经过其中心的特性。我们给出了合成数据的实验结果，表明我们的方法比标准的基于梯度的方法对噪声有更强的鲁棒性。该方法在自然图像和数字化乳房X光照片上的应用证明了该方法的前景。(C)1999 Elsevier Science B.V.保留所有权利。
We present a two-step algorithm for the recognition of circles. The first step uses a 2D Hough Transform for the detection of the centres of the circles and the second step validates their existence by radius histogramming. The 2D Hough Transform technique makes use of the property that every chord of a circle passes through its centre. We present results of experiments with synthetic data demonstrating that our method is more robust to noise than standard gradient based methods. The promise of the method is demonstrated with its application on a natural image and on a digitized mammogram. (C) 1999 Elsevier Science B.V. All rights reserved.
