This is a list of other notable MATLAB programs bundled in VLFeat
vl_imsmooth
smoothes an image by a Gaussian kernel
(simple but very useful as it is generally much faster than MATLAB
general purpose smoothing functions).vl_plotframe
plots a variety of feature frame kinds.vl_binsum
performs binned summations, useful as a
building block for the fast computation of
histograms. vl_whistc
computes weighed histograms.vl_imarray
and vl_imarraysc
arrange and visualize multiple
images in a grid; vl_imsc
scales the image range;
vl_tightsubplot
is similar to built-in subplot
, but
produces narrower margins.vl_cf
makes a copy of a figure.vl_rodr
and vl_irodr
compute the Rodrigues' formula and
its inversevl_override
overrides members of a structure with members of
another structure.vl_imwbackward
warps an image by the inverse mapping method
(generally much faster than MATLAB general purpose warping
functions).vl_waffine
computes the affine warp of a set of
points. vl_tps
, vl_tpsu
, vl_wtps
compute the thin-plate spline warp of a set of points. vl_witps
computes the inverse thin plate warp of a set of point (by
numerically inverting the transformation). They may me used in
combination with vl_imwbackward
.vl_xyz2lab
,
vl_xyz2luv
, vl_xyz2rgb
, vl_rgb2xyz
convert color spaces.vl_rcos
, vl_gaussian
, vl_dgaussian
,
vl_ddgaussian
compute some useful special functions.
