How to convert color image to binary in matlab. The total number of small cubes is: Convert Image To Binary File Codes and Scripts Downloads Free. Another way to do it is to convert RGB to LAB color space with makecform, if you have the image processing toolbox. Then make a new L channel as 100 - the old L channel (to change light to dark), and negate the A channel (to convert green to red), and then convert back to.
Starting in R2014b, MATLAB® graphics has a new color orderthat determines the colors used in plots. This table shows the colororder introduced in R2014b versus previous releases. It also liststhe RGB triplet values that define the colors.
The
ColorOrder
property of the axes containsthe color order. To change the color order, set a different defaultvalue for the ColorOrder
property. For example,this code sets the default color order to the colors used in previousreleases.The hold Command Cycles Through Colors
In R2014a and earlier, the
hold on
commanddoes not retain the current color so new plots added to the axes startfrom the beginning of the color order. Visually, this means that newplots use the same initial color. Starting in R2014b, the holdon
command retains the current color so that new plots addedto the axes use the next colors in the color order.For example, this code displays six lines using the
holdon
command. Starting in R2014b, the lines cycle throughthe color order and the resulting plot uses the first six colors ofthe color order.If you run the same code in previous releases, the color orderrestarts with each plotting command. The resulting plot uses the firstthree colors of the color order twice.
Restart Color Order
Starting in R2014b, if you want to restart the color order beforeeach plotting command, then set the
ColorOrderIndex
propertyof the axes to 1.See Also
Description
ColorSpec
is not a function; it refers tothe three ways in which you specify color for MATLAB® graphics:The short names and long names are character vectors that specifyone of eight predefined colors. The RGB triplet is a three-elementrow vector whose elements specify the intensities of the red, green,and blue components of the color; the intensities must be in the range[0 1]. The following table lists the predefined colors and their RGBtriplet equivalents.
RGB Triplet | ShortName | Long Name |
---|---|---|
[1 1 0] | y | yellow |
[1 0 1] | m | magenta |
[0 1 1] | c | cyan |
[1 0 0] | r | red |
[0 1 0] | g | green |
[0 0 1] | b | blue |
[1 1 1] | w | white |
[0 0 0] | k | black |
Examples
This code makes the x-axis red.
This code changes the figure background color to pink:

Tips
The eight predefined colors and any colors you specify as RGBtriplets are not part of a figure's colormap, nor are they affectedby changes to the figure's colormap. They are referred to as fixed colors,as opposed to colormap colors.
In most cases, you can specify a color using either an RGB tripletor a character vector of a color name. However, in some cases, youcannot specify the color as a color name. For example, you cannotset the
CData
property of a scatter object toa color name.See Also
