數(shù)字圖像處理實驗

1、數(shù)字圖像處理實驗一實驗內(nèi)容圖象統(tǒng)計參數(shù)：最大、小值，均值；圖象平滑：中值濾波，均值濾波；圖象銳化:Sobel算子，Laplace算子；圖象編碼：哈夫曼編碼，行程編碼，算術(shù)編碼，LZW編碼，JPEG編碼圖象恢復(fù)：生成隨機(jī)噪聲，生成椒鹽噪聲，逆濾波復(fù)原，維納濾波復(fù)原，圖象重建；二實驗要求所有實驗均對灰度（8bit）圖象進(jìn)行處理。遞交實驗結(jié)果的可執(zhí)行程序、源程序并演示實驗結(jié)果。如源程序不能提供，請說明理由。遞交實驗報告。要求：寫出選做實驗的實驗原理、實驗結(jié)果，并對實驗結(jié)果進(jìn)行分析。1計算圖像統(tǒng)計參數(shù)I=imread(pout.tif);imshow(I)最大值I=imread(pout.tif);m
