Development of advanced contrast enhancement technique for mammographie images

Abstract

In the present study, we have applied the process of image enhancement to mammographic images. This study has examined the problem of fuzziness/impreciseness of mammograms such as inhomogeneous background, low contrast, indistinct borders, small and ill-defined shapes, varying intensities of the suspicious regions and low distinguishability from their surroundings. Though fuzzy logic based contrast enhancement technique has good potential to handle the problem of impreciseness in mammograms, more generalized and flexible Vague Set theory is appropriate to capture the vagueness of mammograms.
