Abstract
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.
