Hi,
Wondering if is an easy and quick way to add colors to regions in a global map (matrix)?
Like this...(attached figure).
I would like to make a "mask map" with different numbers for the regions (colors) (e.g. South Pacific = 1, North Pacific = 2, etc) and then extract from a global map (matrix) the values for South Pacific = 1, North Pacific =2, etc.
In this case, the global map is a matrix with ocean temperature data.

If you have an image where each region is separated by solid black lines, you can identify each region with bwlabel(), then use label2rgb() to make a colored image
labeledImage = bwlabel(binaryImage);
rgbImage = label2rgb(labeledImage, yourColorMap);
