3D +t
Multi-dimensional Image Analysis |
|||||
|
|
|
The main objective of project is to develop Image Analysis
Tools for Multi-Dimensional (3D +t) Biological Microscopic images, with
emphasis on quantifying the Embryonic Cells as well as their behavior over
time. The entire project has been
divided in to three different pipeline stages as like Pre-processing, Image
stack analysis and temporal tracking stages. Work began with an analysis of
various 3D Morphological techniques to improve the images and their fit for
identifying the homogeneous regions. In the next stage we first isolate the
cells and then track the cell in the time lapse. The final stage of the
project quantifies the cells. |

3D Cell Modeling and
Visualization |
|||||
|
|
|
The main goal of the project is
to develop an accurate and fast algorithm for modeling the Embryonic Cells,
with more emphasis on Cell geometric model and its deformation in the time
lapse. In this project, we intend to
generate a deformation 3D model for reconstructing the accurate dynamic
object shape and also develop an algorithm for rendering labeled texture on
the 3D cell object surface from the segmented images. |
