In our approach, probabilistic priors are generated from prominent features, i.e., corner points and scale-invariant edges, for both endoand epi-cardium segmentation. We adopt a level set formulation that integrates probabilistic priors with intensity, texture, and edge information for segmentation. Our experimental results show that with minimal user input, representative priors are correctly extracted from the data itself, and the proposed method is effective and robust for segmentation of the left ventricle myocardium even in images with very low contrast. More importantly, it avoids inter- and intra- observer variations and makes accurate quantitative analysis of low-quality cardiac MR images possible. © 2009 IEEE.||Source Title:||Proceedings - 2009 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, ISBI 2009||URI:||http://scholarbank.nus.edu.sg/handle/10635/68769||ISBN:||9781424439324||DOI:||10.1109/ISBI.2009.5193181|
