  79.     smart clone tool on steroids</span>‚Äù. And indeed the Healing Tool is a
  80.     close relative to the Clone Tool, but it is more smart to remove small
  81.     failures in images. A typical usage is the removal of wrinkles in
  82.     photographs. To do so, pixels are not simply copied from source to
  83.     destination, but the area around the destination is taken into account
  84.     before cloning is applied. The algorithm used for this, is described in
  85.     a scientific paper by Todor Georgiev
  86.     <a class="xref" href="bibliography.html#bibliography-online-georgiev" title="Image Reconstruction Invariant to Relighting">[<abbr class="abbrev">GEORGIEV01</abbr>]</a>.

  92.     defect is slight, not very
  93.     different from its surrounding, it will be corrected as soon. Else, you
  94.     can correct it with repeated clicks, but with a risk of daubing
