有一功能不知是对图象做了什么处理,请教大家
什么叫调窗啊?使用了什么算法啊?采用了哪种图象处理的方法啊?
软件上的那个功能叫WINDOW SETTINGS。有2个值可以修改,一个是W,一个是C。
使用了什么算法啊?采用了哪种图象处理的方法啊?请赐教!
在文档上有这么一段:
Images or presentation states may contain VOI LUTs, VOI windows, both or none of them.
Per default the first VOI LUT will be selected. If there is no VOI LUT the first VOI window
is selected if existing. Otherwise no windowing is performed on the image, i. e. the full range
of pixel values is displayed on the screen.
If no VOI LUT is selected the window center and width can be modified by a number of
ways. First, the values can be entered directly into the text boxes “c:” and “w:” in the
“Window Settings” panel (fig. 27). Second, the window can be specified interactively by
moving the mouse cursor over the image while pressing the right mouse button.
VOI LUT 是怎么回事啊? |
