抑制數(shù)字圖象中乘性噪聲的方法
THE METHODS FOR REDUCING THE MULTIPLYING NOISE IN THE DIGITAL IMAGES
-
摘要: 本文通過研究數(shù)字圖象中乘性噪聲的特點,提出了以加權相加為主的一些抑制方法。文中用典型的乘性噪聲模型對理論進行了詳細分析,并采用真實的數(shù)據進行了實驗驗證。結果表明:這些方法在處理圖象噪聲方面,比傳統(tǒng)的辦法更優(yōu)越。Abstract: Some new methods for reducing the multiplying noise in the digital images, which are mainly the one of weighting and adding methods, are proposed, after that the characteristics of the noise is studied. The theory is analysed with the common model of multiplying noise and proved by the experiments with real data. It is clear that these methods have more ad-Tantages than traditional ones in processing digital images.
