Working on a collaborative research project which is part of a scientific program called “Total Cryst” (http://www.totalcryst.dk/). The aim is to reconstruct the 2D orientation map of a polycrystals (like metals) from its X-ray diffraction projection data. Knowledge of orientation map is of interest to material scientists since the physical and chemical properties of a polycrystal are related to its orientation map.s

Achieved an improvement in the speed of convergence of the previous algorithm by reducing the randomness of each iterative step. Thus each iteration is costly but the total number of iterations had reduced significantly thereby reducing the time to converge to the final solution.

Got better results than the previous algorithm proposed by L. Rodek.

Code base is C/C++

The research paper will be submitted soon.

Worked on the open source project ITK (www.itk.org) with an aim to improve its performance on the 64-bit-Multiprocessor IRIX machines of SGI for DICOM volume segmentation.

C++ code base with extensive use of templates.

Optimized the Geodesic-Active-Contours filter so that its performance can be scaled with increasing the number of processors.

Computation of data cube operator for a database table in cluster computing environment by designing an efficient load balancing algorithm after properly selecting the views to be materialized.

Algorithm designed was based on the parallel version of Pipesort algorithm.

The thesis was declared to be outstanding
