摘 要 為了快速地去除圖像中的泊松噪聲, 本文在傳統(tǒng)的交替方向算法基礎(chǔ)上, 結(jié)合松弛算法提出了一個(gè)改進(jìn)的快速交替最小化算法. 與經(jīng)典的數(shù)值算法相比,數(shù)值試驗(yàn)表明提出的新算法不但能有效地實(shí)現(xiàn)泊松化圖像復(fù)原, 還能大幅度地提高數(shù)值計(jì)算的速率, 并顯著地減少電腦的CPU運(yùn)行時(shí)間.

Abstract To quickly remove Poisson noise, based on the traditional alternating direction method, this paper combined the relaxation method and proposed an improved alternating minimization algorithm. Compared with the classical numerical algorithm, numerical simulations demonstrate that the proposed strategy not only removes Poisson noise efficiently, but improves the speed of calculation substantially and reduces the computer CPU time noticeably.

Key words image restoration; Poisson noise; total variation; alternating minimization algorithm

1 引 言

圖像在形成、傳輸和存儲(chǔ)過(guò)程中, 不可避免地會(huì)受到噪聲的影響. 譬如, 在天文成像[1]和電子顯微鏡成像[2,3]中, 獲得的圖像就往往會(huì)受到泊松噪聲污染,并出現(xiàn)明顯的降質(zhì)現(xiàn)象,因此圖像復(fù)原就顯得尤為重要. 目前,圖像復(fù)原技術(shù)已在天文學(xué)、醫(yī)學(xué)、刑偵、軍事以及金融學(xué)等領(lǐng)域得到了廣泛的應(yīng)用. 例如,在商業(yè)和金融行業(yè)中,一個(gè)新興的融合信息科學(xué)、金融學(xué)和管理學(xué)的先進(jìn)金融信息技術(shù)(如模式識(shí)別、人工智能等)已有效地應(yīng)用于金融票據(jù)識(shí)別、金融票據(jù)影像處理及打印中,并成功地解決了一系列經(jīng)濟(jì)領(lǐng)域中的熱點(diǎn)和難點(diǎn)問(wèn)題.

4 結(jié) 論

本文研究了一個(gè)基于TV正則化模型的泊松化圖像復(fù)原問(wèn)題. 為了提高數(shù)值計(jì)算的速率, 本文結(jié)合傳統(tǒng)的交替方向法和松弛算法, 提出了一個(gè)改進(jìn)的交替最小化算法. 數(shù)值試驗(yàn)表明, 新算法在泊松去噪中具有顯著的優(yōu)越性和高效性.同時(shí),該算法也必將在金融行業(yè)中的金融票據(jù)識(shí)別和票據(jù)影像處理中得到進(jìn)一步的發(fā)展和應(yīng)用.
