AUTOMATIC DETECTION OF MASSES AND NYLON FIBERS IN MAMMOGRAPHIC PHANTOM IMAGES
Matheus Alvarez, Alexandre França Velo, José Ricardo de Arruda Miranda, Diana Rodrigues de Pina · 2011
This work presents methods for detection of masses in the breast phantom images for quality control of mammography. The methodologies for both are based on Discrete Wavelet Transform (DWT) where the low frequency present in the x-ray image is suppressed, then morphological operations that result in a good location of these objects in the radiograph simulator of the breast are made to quantify the subjective evaluation of specialists in radiology and apply the results of tests in the daily Quality Control (QC).
