未來展望

在本論文的研究與實驗和應用中，發現有數個主題是我們可以繼續改進的重 點，在此說明如下：

1. 本論文是以每秒一張的速率抽取影像，所以判斷主播出現時間的最小單位是

秒，不過影像檔每秒有 29.97 張，若能以跟影像播放相同的速率抽取影像來 偵測主播的話，就能提高判斷主播出現時間的精確度。

2. 本論文實作的人臉偵測與人臉追蹤所花的時間比一般論文所寫的時間多，可 能的原因是在人臉偵測的過程中多了影像分段這個步驟；還有在 3.1.2 節所 提的人臉追蹤在搜尋區域中要比對完所有的位置，從中選擇一個最好的位置，

這個步驟也是會花許多時間，若能在不失精確度的情形下減少時間的花費，

則 1.中所提的建議就能實現。

3. 本論文只取衣服顏色當成每個人的特徵，這步驟的風險在於萬一有其他人穿 的衣服顏色與主播所穿的衣服顏色相同，則此人也會被認為是主播，若能找 到其他更有分別性的特徵則可以大大提升主播段辨識的正確率。
