Mammographic Image Analysis

The key contribution of the approach to X-ray mammographic image analysis developed in this monograph is a representation of the non-fatty compressed breast tissue that can be derived from a single mammogram. The importance of the representation, called hint, is that it removes all those changes in the image that are due only to the particular imaging conditions (for example, the film speed or exposure time), leaving just the non-fatty interesting tissue. Normalizing images in this way enables them to be enhanced and matched, and regions in them to be classified more reliably, because unnecessary, distracting variations have been eliminated.
