In this paper, we propose a new hybrid system for microcalcifications detection in digital mammograms, using the combination of the CDF 9/7 filter bank and a successive approximations threshold. Microcalcifications are low contrast samples and only have a few pixels in diameter which are difficult to detect. We shown that microcalcifications have not only support in high frequency regions, but also along the entire frequency spectrum. The digital mammograms are analyzed and the lowest frequency subband dropped. After recovering the image a successive threshold is calculated to keep the samples with higher amplitudes. Results show that the proposed method reveals accurately the small injuries in digital mammograms. |
