Real Time Edge Detection in HaskellLast week we submitted a paper to ICFP about how to implement efficient parallel stencil convolutions in Haskell. This goes along with a new release of Repa that runs on GHC 7.0.3. We've extended the old array representation to support the partitioning of arrays into several regions, and rewritten the back-end to recover sharing between the computation of adjacent array elements. Coupled with a ca
