(2) These techniques are used for
edge enhancement, image sharpening and image restoration.
In [17], an
edge enhancement approach is proposed by using image fusion technique.
Image quality is ensured by the third generation of Canon's Ultra High Quality (UHQ III) image processing, which combines a special
Edge Enhancement feature to produce photos, illustrations and graphics in 64 shades of gray with greater depth and clarity.
Enhancements fall into the following categories: video enhancement,
edge enhancement, improved X-ray penetration, improved resolution, and inorganic stripping.
Generally speaking, many of the canals appear to be artifacts of
edge enhancement of the boundaries of adjoining regions of different albedo that correspond physically to adjoining surfaces strewn with bright or dusky surface materials.
Computer workstations provided with CR systems permit manipulation of image data to manipulate factors such as contrast and
edge enhancement. However, because of the wide range of variations allowed, it is recommended that only a select few individuals in the radiology department be permitted to change the default processing parameters pre-established by the software.
An
Edge Enhancement feature in UHQ eliminates the fuzzy look often appearing on transmitted text, graphics, and illustrations, and its Error Diffusion Method provides more depth and clarity of halftones.
