Multiphase level sets efficiently segment multiclass multiobject images. Current ITK level sets support the N-level set approach to handle N-objects. Multiphase methods can be applied to a variety of underlying level set energy functions including Chan-Vese, graph partitioning active contours (GPAC), 4-color level sets, and hybrid approaches.

Objective

Multiphase level sets efficiently segment multiclass multiobject images. Current ITK level sets support the N-level set approach to handle N-objects. Multiphase methods can be applied to a variety of underlying level set energy functions including Chan-Vese, graph partitioning active contours (GPAC), 4-color level sets, and hybrid approaches.

Approach, Plan

Extend the current ITK level set class to handle multiphase level sets with support for two, three or a general number of level sets cases. Multiphase methods model [math]N[/math] classes using [math]\log N[/math] phases. Each phase can be used to segment any number of objects. We plan to develop a mechanism for multiphase coupling of multichannel data (i.e. nuclear and membrane channels) with scalar or vector-based energy functions. We plan to include support for 2D and 3D multiphase curve and surface evolution.

Progress

Preliminary multiphase Chan-Vese level set segmentation algorithm has been developed using a Matlab reference implementation. Test cases with synthetic and microscopy imagery have been completed. Need to finish implementation for N-classes, extension to 3D and develop suite of test cases.

NA-MIC Progress

  • Finished multiphase implementation and created preliminary test data for validation of results.
  • Debugging of multiphase update equations for the general N-level set [math]2^N[/math] phase case still continuing.
  • Need to add test cases in ITK for specific 4-phase and 8-phase level set evolution.
