Detection of micro calcification clusters in mammogram images using local maxima and adaptive wavelet transform analysis

In this paper, computer-aided diagnosis of microcalcification clusters in mammogram images is considered. Microcalcification clusters which are an early sign of breast cancer appear as isolated bright spots in mammogram images. Therefore they correspond to local maxima of the mammogram image. In our method we first detect the local maxima of the image, and rank the maxima according to a higher order statistical test performed over the subband domain data obtained by the adaptive wavelet transform.
