VLFeat.jl

Julia wrapper for the VLFeat library.

At this point

1. C functions are wrapped
2. vl_hog(image) provides a HOG descriptor hierarchy of an array or Image object.
3. f,d = vl_sift(image) computes SIFT features and descriptors for an image.

Note that VLFeat seems to assume that Images are Float32 and stored as (color, row, col).

vl_hog will do basic conversion automatically.
