A Location Method for the Key Points of the Skeletal Images Based on Corner Detection

In the research of the automatic bone age assessment,the key points location for the phalanx is the one of key factors,which determines mostly the following research. The key points of phalanx are the most bendest place around the palm. In the article, a common corner detecthon metod is introducted into the medical images. Based on analyzing the principles and shotcomings of the common corner detection algorithms,an improved algorithm is proposed,which is used for the location of the phalangeal key points. Through a large number of experiments and comparisons with other similar methods,the result of an experiment showed that the proposed method is getting a better results in the accurate and fast location,which can be directly applied in the assessment of the bone age age.
