 WDM  WDM = Windows Driver Model In computing, the Windows Driver Model (WDM) - also known (somewhat misleadingly) at one point as the Win32 Driver Model - is a framework for device drivers that was introduced with Windows 98 and Windows 2000 to replace VxD, which was used on older versions of Windows such as Windows 95 and Windows 3.1 and the Windows NT Driver Model.
 Watershed Segmentation  An algorithm is an image processing segmentation algorithm that splits an image into areas, based on the topology of the image. The length of the gradients is interpreted as elevation information. During the successive flooding of the gray value relief, watersheds with adjacent catchment basins are constructed. This flooding process is performed on the gradient image, i.e. the basins should emerge along the edges. Normally this will lead to an over-segmentation of the image, especially for noisy image material. Either the image must be pre-processed or the regions must be merged on the basis of a similarity criterion after wards. A hierarchic watershed transformation converts the result into a graph display and applies further watershed transformations recursively. A problem is that the watersheds will increase in width. The marker based watershed transformation performs flooding starting from specific marker positions which have been either explicitly defined by the user or determined with morphological operators. Interactive watershed transformations allow to determine include and exclude pints to construct artificial watersheds. This can enhance the result of segmentation.
 Watershed Segmentation Number  of Zones  Displays the total number of zones detected in the image.
 White Balance
  A function enabling adjustment of the image colors to make the white objects really appear as white. Thus one can avoid color shifts caused e.g. by differing illumination conditions.
