中文摘要 | 在本文中,我們將應用區域平滑方法(local smoothing method),來估計一張受 干擾的二維影像中的邊界曲線(boundary curve)位置。本文所介紹的邊界曲線位置估計方 法,能夠產生真正粗細一致的曲線估計值。我們的方法沒有目前常用估計方法的缺點,亦即 後者會產生粗細不一致的曲線估計值。模擬研究顯示,本文所介紹的邊界曲線估計方法,即 使在邊界曲線較複雜的影像中,仍有不錯的估計效果。 |
英文摘要 | In this paper, the local smoothing method is applied to estimate the location of the boundary curve in a two-dimensional noisy image. The estimate of If the boundary curve produced by our proposed method is uniformly of the same width. However, the current popular methods do not have this advantage. Simulation studies demonstrate that our proposed method has good performance, even in the case that the true boundary curve has a very complicate shape. |
