Objective
We have developed techniques to achieve cell/nuclei segmentations in microscopic images. Often, nuclei and cells appear as overlapping structures and splitting them apart is a non-trivial problem in image analysis. The microscopy modalities of interest include light, confocal and phase-contrast microscopy.
We have also work on characterizing biological micro-structure in terms of micro-components. This helps us to perform tissue segmentations, clonal population segmentation and tracking. Once again, we propose to incorporate such techniques borrowed from material science and spatial statistics into the microscopy image analysis workflows.
The objectives of this project are to port the ITK-based cell segmentation and micro-structure characterization code to Slicer3 framework.
Approach, Plan
Our approach is based upon using image tessellations and micro-structure characterization algorithms widely used in the material science community. These algorithms help us understand biological organization in terms of component packing densities, arrangements and spatial distributions. The algorithms are detailed in the references provided below. Our main purpose at the Project Week is to work with our collaborators in order to define the scope of this project, decide upon the details of the microSlicer framework in Slicer3, and implement our current developed code into the Slicer3 framework.
Progress
We have currently implemented the cell segmentation algorithm using Geodesics Active Contours and Image-based Voronoi Tessellations in the ITK framework. We have also implemented the microstructure characterization algorithms using the N-Point Correlation functions in ITK. Currently, we are working on building a cell shape model to use in cell segmentations.
