一種改進(jìn)的一致性擴(kuò)散圖像增強(qiáng)方法

An Improved Coherence Diffusion Method for Image Enhancement

  • 摘要: 一致性擴(kuò)散是分析圖像中定向結(jié)構(gòu)的重要的預(yù)處理步驟,現(xiàn)有的一致性擴(kuò)散圖像增強(qiáng)方法難以識(shí)別圖像中的弱邊界.本文提出了一種改進(jìn)的擴(kuò)散方法,該方法構(gòu)建了一種結(jié)合二階方向?qū)?shù)信息的結(jié)構(gòu)張量,能夠精確分析圖像中的復(fù)雜弱邊界,同時(shí)與經(jīng)典結(jié)構(gòu)張量互為補(bǔ)充以檢測(cè)圖像的強(qiáng)邊界.在此基礎(chǔ)上設(shè)計(jì)了新的擴(kuò)散張量,并采用了基于(加性分裂算子AOS)策略的數(shù)值計(jì)算方法.通過對(duì)比實(shí)驗(yàn)證明,該文算法的效果良好并具有很高的效率,實(shí)現(xiàn)了在去除噪聲的同時(shí)精確保護(hù)圖像中的強(qiáng)弱邊界.
