This is a list of other notable MATLAB functions included in VLFeat
vl_imsmooth smoothes an image by a Gaussian kernel
(simple but very useful as it is generally much faster than MATLAB's
general purpose smoothing functions).vl_plotframe plots a variety of feature frame types (such as oriented ellipses).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 gridvl_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 be 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.
