Rather than using this static list, I’d encourage you to visit my Google Scholar page, which I keep updated automatically.

Publications are in reverse chronological order with all types of submissions listed together. As time permits, I will reorganize this and will be adding links to the associated papers, talks, posters, etc.

  5. Weisenfeld NI and Warfield SK. Learning likelihoods for labeling (L3): a general multi-classifier segmentation algorithm. To appear in MICCAI, 2011.
    This work is a generalization of the segmentation strategy that I developed for newborn segmentation (see NeuroImage, 2009, paper below). The new algorithm unifies label fusion and statistical classification.

    In this work with Arne Hans, we address the problem of registration validation and apply our solution to the evaluation of several registration algorithms for capturing "brain shift" during neurosurgery. The key problem is: how do you design a metric that is good for assessing registration accuracy, and therefore image overlap, but is not related to the registration metric used.

    This is one of my key projects and relates to my recent segmentation work. In short, we've developed a new version of the STAPLE algorithm that operates on probabilistic inputs, rather than label maps. That is, instead of observing a label at each voxel from each rater, we observe the probability of every label. This allows us to feed the output of STAPLE back into STAPLE in order to, for instance, separately assess both inter- and intra- individual variability. This also allows us to "fuse" the output of probabilistic classifiers.
