Image Enhancement

What Does Image Enhancement Mean?

Image enhancement is the process of digitally manipulating a stored image using software. The tools used for image enhancement include many different kinds of software such as filters, image editors and other tools for changing various properties of an entire image or parts of an image.


Techopedia Explains Image Enhancement

Some of the most basic types of image enhancement tools simply change the contrast or brightness of an image or manipulate the grayscale or the red-green-blue color patterns of an image. Some types of basic filters also allow changing a color image to black and white, or to a sepia-tone image, or adding visual effects.

More sophisticated types of image enhancement tools can apply changes more specifically to certain parts of an image. Professional packages like those offered by Adobe allow designers to do a more specialized or professional kind of image enhancement or to pursue results for graphic design projects where the actual image is changed into a stylized or otherwise embellished version of itself. More advanced types of image enhancement tools also include features like Wiener filters for actual de-blurring of images and other complex resources for restoring or clarifying images that may be in poor condition, due to sub-optimal image capture conditions, aging or other causes.
