Claim Text:
1. A system for classifying breast density from mammographic imagery using content-based image retrieval, the system comprising: circuitry configured to store a mammogram image database; pre-process one or more digital mammogram images of a patient to remove noise and enhance contrast; segment the one or more digital mammogram images to produce one or more extracted regions of interest and save the one or more extracted regions of interest; group the one or more saved extracted regions of interest to produce a large mammogram image; decompose the large mammogram image by principal component analysis (PCA) in the mammogram image database; and classify the large mammogram image according to breast density with Fisher Linear Discriminant (FLD) in the mammogram image database.
