Mammogram registration is a critical step in automatic detection of breast cancer.Much research has been devoted to registering mammograms using either feature-matching or similarity measure.However, few studies have been done on combining these two methods.In this research, a hybrid mammogram registration method is developed by combining feature-based and intensity-based image registration techniques.Besides, internal and external features were used simultaneously during registration to obtain a global spatial transformation.The experimental results indicate that the similarity between the two mammograms increases significantly after a proper registration using the proposed registration procedures.
