1 簡介

圖像在采集和傳輸過程中可能受到很多外界條件的污染,因此,為了保證圖像提供給我們的信息比較準(zhǔn)確,需要對圖像進(jìn)行去噪處理.通過Matlab軟件分別用高通、低通、帶通、方向多種濾波器對需要的圖像進(jìn)行去噪處理,同時比較幾種去噪方法的優(yōu)缺點,找到對圖像質(zhì)量影響最小,且去噪性能最好的方法.

function PQ = paddedsize(AB, CD, PARAM)%PADDEDSIZE Computes padded sizes useful for FFT-based filtering. % ? PQ = PADDEDSIZE(AB), where AB is a two-element size vector,% ? computes the two-element size vector PQ = 2*AB.%% ? PQ = PADDEDSIZE(AB, 'PWR2') computes the vector PQ such that% ? PQ(1) = PQ(2) = 2^nextpow2(2*m), where m is MAX(AB).%% ? PQ = PADDEDSIZE(AB, CD), where AB and CD are two-element size% ? vectors, computes the two-element size vector PQ. ?The elements% ? of PQ are the smallest even integers greater than or equal to % ?
