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_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_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_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_rgb2xyz convert color spaces.
vl_ddgaussian compute some useful special functions.
