這篇論文中，利用電腦作影像分析去抽取指骨特徵抽取，並使用統計軟體SPSS，去做骨骼生長同步分析的研究。在本文中我們將重點放在生長板的部分，先用手動將生長板切割出來，再抽取了一些指骨生長板的特徵，像是生長板上下的弧度，它的長寬比以及周長面積比等等。之後我們用這些抽取出來的特徵作統計上的比較，以了解各指節之間相對生長的狀況。另外，我們也利用回歸分析去判斷各個特徵的重要性，並分別用他們去做指骨年齡判定，已證明他們的準確性。由於一些指骨年齡判定的研究，常常假設食指、中指以及無名指的生長速度是一樣的，但是並沒有實際的數據去證明這件事。我們就用實際的指骨數據去說明這個假設是否正確。這個研究提供了指節相關度的評估，也證明只用中指即可以提供良好的特徵去做指節年齡的判定。我們也證明了如果用到好的特徵，只用一個指節所做出來的指骨年齡判定，會比用多個指節一起做出來的效果要好。最後實驗結果的指骨年齡判定也令人滿意。只用其中一個特徵判定出的正確率有75.39%(在一歲半的容錯範圍內)，用四個特徵一起判定出的正確率有83.08%(在一歲半的容錯範圍內)。因為通常年齡判定只要在一歲板的誤差之內就算市可以接受。這個結果可以提供給研究指骨年齡判定相關研究的人士，一個參考的依據。

The thesis investigates whether the bone growth of each phalange exhibits synchronization by analyzing the phalanxes’ features statistics via some computer image processing techniques and SPSS. Some features from the epiphysis, like radian of the epiphyseal, the ratio of width and thickness of the epiphyseal, the ratio of circumference of epiphyseal divided by area of epiphyseal, and so on are used in the investigation. Some physicians hypothesize that the second, third and fourth phalanges grow synchronously. We use the actual phalangial data to check if the hypothesis is right or not. The study not only makes a correlation evaluation of phalanxes but supports direct evidence that a feature of middle finger could be used as a good index to describe the bone age.
