ACTIVE PROJECTS

 

 

 

 

    

   3D +t Multi-dimensional Image Analysis Tool for the Study of Cell Cycle Progression

 

 

 

 

The main objective of project is to develop Image Analysis Tools for Multi-Dimensional (3D +t) Biological Microscopic images, with emphasis on quantifying the Drosophila embryo Cell nuclei as well as study the dynamics of cell division.  The entire project has been divided in to three different pipeline stages as like Pre-processing, 3D nuclei segmentation and cell nuclei tracking. Work began with an analysis of various background / foreground detection methods and their fit for identifying the background and foreground regions in the image stack. In the next stage we isolate the cell nuclei from the foreground. The final stage of the project quantifies the cell nuclei.

Cell Nuclei Cycle Visualization and Navigation  Tool

 

 

 

The main goal of the project is to develop a tool for visualizing the dynamics of cell nucleus division. In this project, we intend to create scenes for different cell cycle tracks and flythrough navigations in the scenes by using X3D platform.
