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
