This article is a list of the color palettes for notable computer graphics, terminals and video game console hardware.. Only a sample and the palette's name are given here. More specific articles are linked from the name of each palette, for the test charts, samples, simulated images, and further technical details (including referenc
A linear, or axial, color gradient. In color science, a color gradient (also known as a color ramp or a color progression) specifies a range of position-dependent colors, usually used to fill a region. In assigning colors to a set of values, a gradient is a continuous colormap, a type of color scheme.
Each tool is highly customisable, and comes with several presets. It is possible to share custom resources between users and there is a reasonably active ArtRage community that creates and shares presets, canvases, custom brushes, stencils, colour palettes, and other resources.
The pixels with the largest gradient values in the direction of the gradient become edge pixels, and edges may be traced in the direction perpendicular to the gradient direction. One example of an edge detection algorithm that uses gradients is the Canny edge detector. Image gradients can also be used for robust feature and texture matching.
The evolution of digital color grading tools has advanced to the point where the colorist can use geometric shapes (such as mattes or masks in photo software such as Adobe Photoshop) to isolate color adjustments to specific areas of an image. These tools can highlight a wall in the background and color only that wall, leaving the rest of the ...
The fractional gradient is defined as the speed point at which the slope of the characteristic curve first reaches a fixed fraction (e.g. 0.3) of the average gradient over a range (e.g. 1.5) of the characteristic curve. [2]
