Automatic Mass Segmentation Based on Adaptive Pyramid and Sublevel Set Analysis
Fei Ma, Mariusz Bajger, Murk J. Bottema · 2009
A method based on sublevel sets is presented for refining segmentation of screening mammograms. Initial segmentation is provided by an adaptive pyramid (AP) scheme which is viewed as seeding of the final segmentation by sublevel sets. Performance is tested with and without prior anisotropic smoothing and is compared to refinement based on component merging. The combination of anisotropic smoothing, AP segmentation and sublevel refinement is found to outperform other combinations.
