摘要: | Slope transform最近幾年被應用到影像處理,它在非線性訊號處理的角 色正如同傅立葉轉換在線性訊號處理的角色一般,本篇論文提供一種使用 Slope transform處理影像還原的方法。首先我們把整個處理過程用數學 模式描述,再用一些例子來解釋整個處理過程,及處理過程中發生的問題 ,然後用已知的結構元素來還原整張受污染的影像。最後,在不知道結構 元素的情況下,用測試影像得到結構元素,然後還原受污染的影像。 Slope transform is often applied to image processing in recent years. It takes a part in nonlinear signal processing similar to Fourier transform in the linear signal processing. The thesis proposes a method to image restoration using Slope transform. We first give mathematics model and some examples to state the proposed method and problems. Then, using known structuring element to restore a dilated image. Finally, using a test image and its dilated image to achieve structuring element. After this, any distorted image by a same dilation-like distortion can be restored. |
