Distressing (or weathered look) in the decorative arts is the activity of making a piece of furniture or object appear aged and older, giving it a "weathered look". There are many methods to produce an appearance of age and wear. [1] Distressing is viewed as a refinishing technique although it is the opposite of finishing in a traditional sense ...
In photography and optics, vignetting (/ vɪnˈjɛtɪŋ /; vin-YET-ing) is a reduction of an image's brightness or saturation toward the periphery compared to the image center. The word vignette, from the same root as vine, originally referred to a decorative border in a book. Later, the word came to be used for a photographic portrait that is ...
Distress Flying the flag upside-down, [note 2] or tying it into a wheft. [1] Half-mast. Main article: Half-mast. A style of flag display where the flag is flown at least the width of the flag between the top of the flag and the top of the pole. Typically used as a display of mourning or rememberence. Hoist The act or function of raising a flag ...
e. Edge detection includes a variety of mathematical methods that aim at identifying edges, defined as curves in a digital image at which the image brightness changes sharply or, more formally, has discontinuities. The same problem of finding discontinuities in one-dimensional signals is known as step detection and the problem of finding signal ...
Edge-preserving filters are designed to automatically limit the smoothing at “edges” in images measured, e.g., by high gradient magnitudes. For example, the motivation for anisotropic diffusion (also called nonuniform or variable conductance diffusion) is that a Gaussian smoothed image is a single time slice of the solution to the heat ...

Typographic alignment. In typesetting and page layout, alignment or range is the setting of text flow or image placement relative to a page, column (measure), table cell, or tab (and often to an image above it or under it). The type alignment setting is sometimes referred to as text alignment, text justification, or type justification.
Unsharp masking (USM) is an image sharpening technique, first implemented in darkroom photography, but now commonly used in digital image processing software. Its name derives from the fact that the technique uses a blurred, or "unsharp", negative image to create a mask of the original image. The unsharp mask is then combined with the original ...
