中文摘要 | 在本文中,我們將應用區域平均方法〈local average method),來估計一張受干 擾的二維影像〈two dimensional image)中的連續曲線(continuous curve)位置。這貍所謂 的曲線是指影像中的極細長區域,在其具有最大寬度之處,只能涵蓋影像中少數幾個取樣點 〈pixel)。模擬研究顯示,本文所介紹的達續曲線位置估計方法,即使在曲線較複雜的情況 中,仍有不錯的估計效果。 |
英文摘要 | In this paper, the local average method is applied to estimate the location of the continuous curve in a two-dimensional noisy image. Here, the so-called continuous curve stands for the very thin and narrow area in the image. The width of the continuous curve can only covers a few number of pixels. Simulation studies demonstrate that our proposed method has good performance, even in the case that the true continuous curves in the image are complicate. |
