DOQ Digital orthophoto quadrangle raster image format, used for aerial photos
that are processed to remove distortion. A typical DOQ represents one quarter
of a USGS topographic map at 1:24 000 scale.

edge enhancement filters Filters that improve the quality of an image by
extracting individual elements, such as boundaries and property lines. You
can also use these filters for object extraction or object recognition by
higher-level algorithms.

embed To store a raster image in a drawing, rather than as a file external to
the drawing. Embedded images can be viewed in an AutoCAD-based
application only if the application is installed with AutoCAD Raster Design
or the Object Enabler for AutoCAD Raster Design.

Enable Mask A ProdNameShort option on the Image Mask Properties tab that
enables an existing mask for display. Enabling allows you to view the image
clip as defined by the image mask.
