Abstract

Magnetic resonance imaging (MRI) has higher sensitivity than mammography in breast cancer detection. However, the low contrast images produced often process difficulties in segmenting the images into regions of interest. There are various contrast enhancement techniques proposed over the years. Although these techniques shows evident contrast enhancement on general images, most of them are not suitable to apply to breast MRI images due to large portion of dark background and close gray levels between grandular tissues and fatty tissues. In this paper, a modified version of hyperbolic logarithm contrast enhancement technique is introduced. Comparisons are made visually and statistically with several existing contrast enhancement techniques.
