The results indicate improved image quality, which will help radiologists in the diagnosis process. Future research will use this technique as a preprocessing step in full-scale space approaches for automatic or human-assisted semiautomatic classification methods. [PERSON] and [PERSON] designed the proposed algorithm. [PERSON] and [PERSON] applied the image processing algorithms to the mammograms. [PERSON], [PERSON], and [PERSON] defined the set of analyzed cases. All the authors contributed to the writing and review of the paper.
