在Matlab中的颜色 [英] colormap in matlab

问题描述

对于色彩图，如何强调一些调光功能的亮度？

For a colormap how do you accentuate the brightness of some of the dimmer features?

推荐答案

href =http://www.mathworks.com/access/helpdesk/help/techdoc/ref/brighten.html =nofollow noreferrer> BRIGHTEN 函数来加亮整个 > colormap，从而使调光器特征变亮：

You can use the BRIGHTEN function to brighten the entire colormap, thus brightening the dimmer features as well:

brighten(0.5);  %# Brightens the current colormap

%# OR...

newMap = brighten(oldMap,0.5);  %# Brighten the colormap in variable oldMap
colormap(newMap);               %# Update the current colormap to newMap

调光器功能（即只是色彩映射的部分），您必须首先决定如何对作为调光器功能的内容进行分类。 ;）

If you want to brighten only the dimmer features (i.e. just part of the colormap), you have to first decide how to classify what counts as a "dimmer" feature. ;)
