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 andvl_imarraysc arrange and visualize multiple images in a gridvl_imsc scales the image range;vl_tightsubplot is similar to built-insubplot, but produces narrower margins.vl_cf makes a copy of a figure.vl_rodr andvl_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 withvl_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.
