A microcalcification enhancement method for mammogram images

This paper proposed a novel method to enhance mammogram images used in detecting early signs of breast cancer. The proposed method uses a three level pyramid decomposition scheme that applies the squeeze box filter (SBF) instead of low-pass filtering. A previously proposed non-linear local enhancement technique is applied to the difference images to contrast enhance the structural details of a mammogram image. The enhanced mammogram image is reconstructed by adding the enhanced difference images to the original SBF processed image. The experiment and preliminary results reported in this paper provide evidence of beneficial enhancements provided by the proposed method on mammographic images.
