    Abstract: 本文使用個人電腦為平台,再加上影像處理的方法來作影像追蹤系統。影像經由小波轉換至頻域,在頻域下建立低頻子影像,並利用此子影像進行影像差分,再經由二值化、侵蝕、擴張等影像處理技術,找出影像的邊緣或物件外框,再利用找出的邊緣或外框算出幾何中心的位置,並與影像原來的中心位置做比較,進而搭配步進馬達來控制CCD攝影機作位移回饋,使CCD攝影機能即時追蹤並監控移動的物體。

    本實驗分為三個階段 :第一階段為影像之小波轉換,目的是利用小波轉換的特性處理平時時域不易處理之問題;第二階段為影像處理技巧,目的在找出
    Based on a PC platform, an image tracking system is established by applying the image treatment method. The image is converted to the frequency subbands via the wavelet transform. The sequence of subimages with low frequency is used for image differencing
