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 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 inverse`vl_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.
