1、第16頁(yè)共16頁(yè)課程設(shè)計(jì)(論文)說明書題目:數(shù)字圖像處理的MATLAB實(shí)現(xiàn)第16頁(yè)共16頁(yè)摘要利用matlab的GUI程序設(shè)計(jì)一個(gè)簡(jiǎn)單實(shí)用的圖像處理程序。該程序應(yīng)具備圖像處理的常用功能,以滿足用戶的使用?,F(xiàn)設(shè)計(jì)程序有以下基本功能:1.圖像的讀取和保存。2.設(shè)計(jì)圖形用戶界面,讓用戶能夠?qū)D像進(jìn)行任意的亮度和對(duì)比度變化調(diào)整,顯示和對(duì)比變換前后的圖像。3.設(shè)計(jì)圖形用戶界面,讓用戶能夠用鼠標(biāo)選取圖像感興趣區(qū)域,顯示和保存該選擇區(qū)域。4.編寫程序通過最近鄰插值和雙線性插值等算法將用戶所選取的圖像區(qū)域進(jìn)行放大和縮小整數(shù)倍的操作,并保存,比較幾種插值的效果。5.圖像直方圖統(tǒng)計(jì)和直方圖均衡,要求顯示直方圖統(tǒng)計(jì)
2、,比較直方圖均衡后的效果。6.能對(duì)圖像加入各種噪聲,并通過幾種濾波算法實(shí)現(xiàn)去噪并顯示結(jié)果。關(guān)鍵詞:圖像;截圖;縮放;直方圖;加噪去噪第16頁(yè)共16頁(yè)AbstractUseofmatlabGUIprogrammingasimpleandpracticalimageprocessingprogram.Theprogramshouldhavethecommonuseoftheimageprocessingfunction,tomeettheuser'suse.Nowhasthefollowingbasicfunctiondesignprogram:1.Theimageofthereadingands
