提出一种魔棒选择工具的具体实现方法，它已在最新推出的图象处理软件中得到实际的应用。
In this paper, a concrete realization method of the magic wand selection tool is proposed. Which is applied successfully in our image processing software.
提示：确认在图层面板中，图像的图标出于选中状态，而不是蒙版图标。否则魔棒工具会选择整个图片。
(Note: Make sure your image icon is selected in your layers palette, not your mask icon otherwise your magic wand will select your whole image).
所以我们用可以快速选择的魔棒工具(W key)在画面中手臂的外面点一下，然后点击Ctrl + Shift + I来反相选择。
So we can grab the Quick selection Tool (w key) and make a selection outside and the hand, and hit Ctrl + Shift + I to inverse the selection.
