The paper summarizes the design and implementation
of a quadratic edge detection filter, based on Volterra series,
for enhancing calcifications in mammograms. The proposed
filter can account for much of the polynomial nonlinearities
inherent in the input mammogram image and can replace the
conventional edge detectors like Laplacian, gaussian etc. The
filter gives rise to improved visualization and early detection of
microcalcifications, which if left undetected, can lead to breast
cancer. The performance of the filter is analyzed and found
superior to conventional spatial edge detectors |
