This is a list of other notable MATLAB functions included in VLFeat
vl_imsmoothsmoothes an image by a Gaussian kernel (simple but very useful as it is generally much faster than MATLAB's general purpose smoothing functions).vl_plotframeplots a variety of feature frame types (such as oriented ellipses).vl_binsumperforms binned summations, useful as a building block for the fast computation of histograms.vl_whistccomputes weighed histograms.vl_imarrayandvl_imarrayscarrange and visualize multiple images in a gridvl_imscscales the image range;vl_tightsubplotis similar to built-insubplot, but produces narrower margins.vl_cfmakes a copy of a figure.vl_rodrandvl_irodrcompute the Rodrigues' formula and its inversevl_overrideoverrides members of a structure with members of another structure.vl_imwbackwardwarps an image by the inverse mapping method (generally much faster than MATLAB general purpose warping functions).vl_waffinecomputes the affine warp of a set of points.vl_tps,vl_tpsu,vl_wtpscompute the thin-plate spline warp of a set of points.vl_witpscomputes 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_rgb2xyzconvert color spaces.vl_rcos,vl_gaussian,vl_dgaussian,vl_ddgaussiancompute some useful special functions.
