資源簡(jiǎn)介
基于改進(jìn)暗通道的去霧算法圖像增強(qiáng)與圖像修復(fù)二者之間有一定交叉，盡管它們一個(gè)強(qiáng)調(diào)客觀標(biāo)準(zhǔn)，一個(gè)強(qiáng)調(diào)主觀標(biāo)準(zhǔn)，但畢竟最終的結(jié)果都改善了圖像的質(zhì)量。圖像去霧就是這兩種技術(shù)彼此交叉領(lǐng)域中最典型的代表。如果將霧霾看作是一種噪聲，那么去除霧霾的標(biāo)準(zhǔn)顯然是非常客觀的，也就是要將圖像恢復(fù)至沒(méi)有霧霾下所獲取的情況。但是如果將在霧霾環(huán)境下拍攝的照片就看作是一種圖像本來(lái)的面貌，那么去霧顯然就是人們?yōu)榱烁纳浦饔^視覺(jué)質(zhì)量而對(duì)圖像所進(jìn)行的一種增強(qiáng)
