This tool was once described as “The healing brush looks like a smart clone tool on steroids”. And indeed the Healing Tool is a close relative to the Clone Tool, but it is more smart to remove small failures in images. A typical usage is the removal of wrinkles in photographs. To do so, pixels are not simply copied from source to destination, but the area around the destination is taken into account before cloning is applied. The algorithm used for this, is described in a scientific paper by Todor Georgiev [GEORGIEV01].
