    Vectorize corner matching function · ee674323
    David Barker authored
    Add an SSE4 version of compute_cross_correlation() from
    corner_match.c. This function is about 3.4x the speed of
    the scalar code; determine_correspondence as a whole is about
    2.5-3x the speed it was previously.
