Stake. Gradient maps are both at the center and at the basic level of map making on Wikipedia. A simple blank map and fill with color tool are needed. To continue to build a coherent Wikipedia display, this page suggests the most suitable SVG source files together with a blue-based color ramps from academic, screen friendly, print friendly, and color-blind friendly ColorBrewer2 by cartography ...
Maps that highlight one subject area, primarily for species distributions. Locator maps: a country (red) in its region and in the world (corner map). Multi-area: ranges of animals species, languages. /Gradient maps: Areas colored to show a numerical statistic: Population density, per-capita income /Historical maps (en) Historical maps. Complex ...
Ordered dithering is any image dithering algorithm which uses a pre-set threshold map tiled across an image. It is commonly used to display a continuous image on a display of smaller color depth . For example, Microsoft Windows uses it in 16-color graphics modes.
Image color transfer is a function that maps (transforms) the colors of one (source) image to the colors of another (target) image. A color mapping may be referred to as the algorithm that results in the mapping function or the algorithm that transforms the image colors.
Area maps or distribution maps display one or multiple entities on a map, and are closely link to Locator maps (blank) (mother) providing the background & Historical maps (daughter) providing conventions for associated labels, icons, and legend. Historical label/icons conventions may also be used for other purpose, such as complex biology maps ...
The program did a good job on the map boundaries (the most tedious task in the tracing) and the settings dropped out all the text (small objects). The text was manually re-inserted. Map in PNG format (13 kB) Map after automated conversion and touch up to re-add the labels and adjust colors (18 kB) Other conversions may not go as well.
Local minima of the gradient of the image may be chosen as markers, in this case an over-segmentation is produced and a second step involves region merging. Marker based watershed transformation make use of specific marker positions which have been either explicitly defined by the user or determined automatically with morphological operators or ...
