This is a list of other notable MATLAB programs bundled in VLFeat

  • imsmooth smoothes an image by a Gaussian kernel (simple but very useful as it is generally much faster than MATLAB general purpose smoothing functions).
  • plotframe plots a variety of feature frame kinds.
  • binsum performs binned summations, useful as a building block for the fast computation of histograms. whistc computes weighed histograms.
  • imarray and imarraysc arrange and visualize multiple images in a grid; imsc scales the image range; tightsubplot is similar to built-in subplot, but produces narrower margins.
  • cf makes a copy of a figure.
  • rord and irodr compute the Rodrigues' formula and its inverse
  • override overrides members of a structure with members of another strucutre.
  • imwbackward warps an image by the inverse mapping method (generally much faster than MATLAB general purpose warping functions).
  • waffine computes the affine warp of a set of points. tps, tpsu, wtps compute the thin-plate spline warp of a set of points. witps computes the inverse thin plate warp of a set of point (by numerically inverting the transformation). They may me used in combination with imwbackward.
  • xyz2lab, xyz2luv, xyz2rgb, rgb2xyz convert color spaces.
  • rcos, gaussian, dgaussian, ddgaussian compute some useful special functions.
