Converts a labeled image to an RGB image.
label2rgb(L) returns a color image, where the background color (the background is the zero-labeled pixels) is white, and all other colors come from the
jet
colormap.label2rgb(L, map) uses colors from the given colormap. map can be
- A string containing the name of a function to be called to produce a colormap. The default value is "jet".
- A handle to a function to be called to produce a colormap.
- A N-by-3 colormap matrix.
label2rgb(L, map, background) sets the background color. background can be a 3-vector corresponding to the wanted RGB color, or one of the following strings
- ‘"b"’
- The background color will be blue.
- ‘"c"’
- The background color will be cyan.
- ‘"g"’
- The background color will be green.
- ‘"k"’
- The background color will be black.
- ‘"m"’
- The background color will be magenta.
- ‘"r"’
- The background color will be red.
- ‘"w"’
- The background color will be white. This is the default behavior.
- ‘"y"’
- The background color will be yellow.
label2rgb(L, map, background, order) allows for random permutations of the colormap. order must be one of the following strings
- ‘"noshuffle"’
- The colormap is not permuted in any ways. This is the default.
- ‘"shuffle"’
- The used colormap is permuted randomly.
