Bringing forward an intelligent decision method of image segmentation based on roughset theory to make the system automatically select segmentation algorithm in simple scenes. firstly, it selects some representative segmentation algorithms to make up of an algorithm library, which is used to process kinds of sample images ; secondly, it makes the decision informationtable utilizing diversified numerical features extracted from the sample images and the optimalsegmentation algorithm of each sample image according to segmentation quality evaluationcriterion ; finally, it applies rough set theory on discretization and attribution reduction of
為了使系統在簡單場景下能夠通過自動選取分割演算法來提取目標，提出了一種基於粗糙集理論的圖像分割智能決策方法。首先選取若干具代表性的分割演算法構成演算法庫，並用它們對各種樣本圖像進行分割;然後利用從樣本圖像中提取出來的各種數值特徵，並根據圖像分割質量評價標準評判出各樣本圖像的最優分割演算法，用其構成決策信息表;最後應用粗糙集理論來對決策信息表進行離散化處理和屬性約簡，以生成圖像分割演算法選取的決策規則。On the following, on the basis of formulas given above, three kinds of effects due to ionosphere are presented : image shift due to group delay which was caused by the difference between the group velocity and the velocity of light in the ionosphere ; image distortion due to ionospheric dispersion which can create second phase error of lfm signals ; the last, the phase perturbation caused by the irregularities of the ionosphere can reduce the coherent length and affect azimuthal resolution
文中主要研究了電離層的三種影響：信號經過電離層傳播的群延遲引起的成像偏移；電離層的色散效應給線性調頻信號帶來二次相位誤差，導致圖像退化、失真；以及電離層的閃爍、湍流等不規則性引起的信號相位起伏。在此基礎上，比較分析了不同波段、帶寬條件下電離層的影響。
