Literature reviews

In this chapter, we review the techniques of histogram equation, hand bone segmentation and image segmentation techniques. The basic concepts of those techniques will be analyzed and compared. The objective of this chapter is to show to readers that current techniques are not sufficient to address the hand bone segmentation problems due to various restrictions. Hence, this motivates the need for new technique that is capable of segmenting the hand bone so that the segmented hand bone can be established and implemented in the fully automated computer-aided skeletal age scoring system. The proposed novel framework of hand bone segmentation will then be presented in next Chap. 3
