In this paper, one method for bilateral registration and intensity normalization and two methods for difference analysis are described. The bilateral registration is based on anatomical features and assumptions of how the female breast is deformed under compression. The first method for differential analysis is based on the absolute difference between the registered images while the second method is based on statistical differences between properties of corresponding neighborhoods. The methods are tested on images from the MIAS database (on 100 images with 59 abnormalities distributed over four types) and evaluated by FROC-analysis. The performances of the two methods are similar but the statistical method gives better performance at a lower false positive rate and is better in particular for detecting asymmetrical developments. <\/jats:p>","DOI":"10.1142\/s0218001403002812","type":"journal-article","created":{"date-parts":[[2003,11,12]],"date-time":"2003-11-12T05:40:51Z","timestamp":1068615651000},"page":"1207-1226","source":"Crossref","is-referenced-by-count":12,"title":["DIFFERENTIAL ANALYSIS OF BILATERAL MAMMOGRAMS"],"prefix":"10.1142","volume":"17","author":[{"given":"FREDRIK","family":"GEORGSSON","sequence":"first","affiliation":[{"name":"Department of Computing Science, Ume\u00e5 University, SE-901 87 Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/S0734-189X(86)80047-0"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1142\/9789812797834"},{"key":"rf3","volume-title":"Anatomisk Bildatlas","author":"Brinkman I.","year":"1987"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1007\/978-94-011-5318-8_46"},{"key":"rf10","unstructured":"F.\u00a0Georgsson and P.\u00a0Eklund, Fuzzy and Neuro-Fuzzy Systems in Medicine, eds.
