The estimation of discrete tangent is an important step in the analysis of images.An improved algorithm of discrete tangent estimation is proposed,which is based on the recognition of discrete straight segments.For each point of a digital curve,the longest discrete segment passing the point is first detected,and this segment is considered as the discrete tangent.To compare the new algorithm and a traditional one,a lot of experiments were conducted on the digital circles and digital ellipses in a wide range of resolution.For each curve,the maximum and the mean of errors are recorded.Experimental results show that the new method has an overall good performance.

在图像分析中,离散曲线的切线估计是一个重要的步骤。作者提出一种基于离散直线段识别的切线估计算法,对于离散曲线上的每一点,通过寻找过该点的最长离散直线段来估算该点的切线。为了检测新算法的有效性和精确性,新算法与传统算法被用在不同精度的圆和椭圆上进行实验,实验比较了两种不同算法的平均错误和最大错误,实验结果表明新算法具有更好的性能。
