Aims at application , we mainly discuss face detection in two circumstance . ( 1 ) in the gray image , we use difference image in multi - frames , then get the edge of the face , we make the raw - location to ensure the approximate position of the face , next , we use the template of the face to occlude the pseudo face region and get the region which near the exact face region . ( 2 ) use method of two template matching , first , we get the face template from many face average , second , we copy the eye section of the face template then get the eye template 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(cè)定位,針對(duì)實(shí)際應(yīng)用的要求,著重處理了兩種情況的人像檢測(cè)定位: ( 1 )在灰度圖像下對(duì)連續(xù)輸入的多幀進(jìn)行差分,對(duì)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(cè)中采取了首先使用尺度相對(duì)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(lái),采用的是暫態(tài)行波信號(hào),首先將三相信號(hào)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(lái)確定行波到達(dá)時(shí)間。
