Mixed raster content
Encyclopedia
Mixed raster content or MRC is a process of using image segmentation
methods to improve the contrast
resolution
of a raster image composed of pixel
s. The decomposition of an image using segmentation approaches separates image objects on a foreground and background plane that can be viewed separately or as a composite with the other layer or layers. Generally, MRC is wrapped into a hybrid file format, which supports markup language (like XML
) embedding in the same file structure.
Segmentation (image processing)
In computer vision, segmentation refers to the process of partitioning a digital image into multiple segments . The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyze...
methods to improve the contrast
Contrast (vision)
Contrast is the difference in visual properties that makes an object distinguishable from other objects and the background. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view...
resolution
Display resolution
The display resolution of a digital television or display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by all different factors in cathode ray tube , flat panel or projection...

Pixel
In digital imaging, a pixel, or pel, is a single point in a raster image, or the smallest addressable screen element in a display device; it is the smallest unit of picture that can be represented or controlled....
