  • Improve segmentation algorithms initialization for nuclei detection in 3D fluorescent microscopy:
    • get a better accuracy,
    • improve computation speed.

Approach, Plan

  • Compare different algorithms,
  • Find a measure to evaluate different algorithm results,
  • Fusion output of several algorithms.


  • Implemented algorithms in ITK:
    • Radial voting,
    • Multi-scale Distance Map weighted Laplacian of Gaussian.
  • Created a collaboration framework using ITK:
    • Set of utilities for input images normalization
    • Developed a windowed local maxima filter
  • Evaluated and compared output of on synthetic 2D data & 3D Nuclei channel from Megason Lab
    • Multi-scale Distance Map weighted Laplacian of Gaussian.
    • Radial voting


  • Implement state of the art seeding algorithms with ITK
    • gradient flow tracking
  • Evaluate new algorithms
