Abstract
⺠The definitions of the discrete derivatives provide a simple and reliable way to estimate the derivatives from discrete curves. ⺠Based on the discrete derivatives, the geometric properties are estimated directly from discrete data points by using differential geometry theory. ⺠The geometric properties estimation method has good performance, and is robust to noise and suitable for different curve shapes.
