COMPLETED PROJECTS

“Game Development -Beat the Dealer Simulator - VC++” May 2011

• A card game code in OOPS designed to have several instance of players to play with a dealer

• Examined, employed exclusive random number generators and developed a console application.

“Earliest Option between Air Terminals – C# .NET” January 2011

• An earliest option for a given schedule for any source to destination using in-memory data structures

• Employed Dictionary and data structures such as Graphs, Dijkstra algorithm, Stack to store, process, retrieve airline information and calculate between nodes (airports) using C#.net.

“Implementation of Pattern Recognition Algorithms on Raw Images Using C & C# .NET” May 2009

• Programmed managed codes to separate images into blocks of desired size after zero padding and then applied recursive 2D FFT of each image blocks and then made a phase plot and magnitude plot of any images (color /BW/ grayscale) to see the effect of the patterns. OOPS being followed methods could serve as dynamic link libraries.
