This is a project is about identifying and parameterizing the precursors of neuronal cells within early-stage embryos. We will co-register the names with the cells due to their general location, and we collect quantitative data about static location after division and vectors that describe shape changes and overall positional changes in the embryo. For this, we need to develop image segmentation tools, which is the top priority of my proposal, to assist further development of this project. My approach, in nutshell, is to try out a variety of segmentation techniques to achieve the top priority of this project. The project will conclude with a development of a proper ImageJ plugin which will facilitate application of our approach on other databases.
