文中首先介紹了圖像預(yù)處理的各種方法，重點(diǎn)介紹了圖像分割和人臉檢測定位，針對實(shí)際應(yīng)用的要求，著重處理了兩種情況的人像檢測定位： ( 1 )在灰度圖像下對連續(xù)輸入的多幀進(jìn)行差分，對于得到的邊緣進(jìn)行處理初步確定人像的大概位置，然后采用模板匹配進(jìn)行精確定位。 ( 2 )應(yīng)用雙模板匹配的方法，由多人臉平均得到人臉模板和眼睛模板，在檢測中采取了首先使用尺度相對較小的雙眼模板搜索候選人臉，再用人臉模板匹配進(jìn)一步篩選候選人臉的方法。 - In the second method , wavelet transform is combined with modal transform , and transient travelling - wave signal is used . after three phase signals are decomposed into their modal components , the wavelet transform coefficient of ground mode can be used to identify approximate position of fault , and the wavelet transform coefficient of aerial mode is used for identifying arrival time of traveling - wave
第二種方法將小波變換與模式變換理論結(jié)合起來，采用的是暫態(tài)行波信號，首先將三相信號轉(zhuǎn)換成模式分量，零模分量的小波變換系數(shù)用于判別故障的大致位置，然后利用線模分量的小波變換系數(shù)來確定行波到達(dá)時(shí)間。 - It's difficult to find approximate positioning in a sentence. 用approximate positioning造句挺難的
