Teaching Experiences:

• 2009, Teaching Assistant in "Applied Estimation", KTH.
• 2010, Teaching Assistant(one session) in "Applied Estimation", KTH. Introduction to Vectorized Processing in MATLAB , Sample Codes for Vectorized processing in MATALB

Code:

• Iterative methods for computation of Fundamental matrix: The package contains MATLAB implementation of the iterative algorithms suggested in Hartley and Zisserman's Multi View Geometry.
• Nonlinear Coupled Diffusion: The package contains MATLAB implementation of Weickert's Nonlinear Coupled Diffusion.
• A Sparse Set of Features for Texture Discrimination: The package contains MATLAB implementation of Brox's feature set.
• Gaussian Mixture Models on Cuda Mex(Binary) [Requires Fermi Cards]: The package contains linux 64 bit binaries for learning(Expectation Maximization) and evaluating multi dimensional gaussian mixture models using GPU acceleration.
• Isotropic Multi Dimensional Kernel Density Estimation on Cuda Mex(Binary) [Requires Fermi Cards]: The Linux 64 bit binary for MDKDE(Isotropic) using GPU acceleration.
• Dense distance computations between two sets of points(Binary) [Requires Fermi Cards]: The Linux 64 bit binary for dense distance computations including P norms(L_1, L_2 and L_inf), Chi squared distance and Histogram Intersection between two sets of points(or histograms) using GPU acceleration. The code is tuned to handle large dimensions and large sets (when the distance matrix does not fit on device memory).
