However, the significant complexity of breast anatomy results in suboptimal imaging of specific breast regions, such as breast periphery and dense mammary gland. The inhomogeneity of mammographic image quality can be dealt with by application of the so- called exposure or grey level equalisation techniques. This monograph provides the reader with a structured presentation of several equalisation ...
