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. |
