Research

I am interested in computer vision, pattern recognition, machine learning, physics, math, functional programming.

easyVision, a Haskell system for computer vision and image processing.
hmatrix, a Haskell library for linear algebra and numerical computation.
hTensor, a Haskell package for multidimensional arrays and tensor computations.
