Metoda detekcji guzków w obrazach mammograficznych wykorzystująca transformację Rayleigha

Breast cancer is one of the most dangerous tumors for middle-aged and older woman, and mammography is its most reliable early detection method. In this paper, a fully automated method for detection of mass-like objects is proposed. The main stage of the algorithm is non-linear histogram conversion based on Rayleigh transformation. That approach gives us mammograms with significantly improved masses visibility and, thus, easier way to segment a potential mass object. Achieved results confirm the usefulness proposed method for application in mammography-oriented content-based image retrieval system and are comparable to to other state-of art methods.
