Getting color intensity values
조회 수: 12(최근 30일)
I'm trying to get color values for single points that I can then use to plot these points in sort of a "intensity scatter plot"
I would ideally like to set the caxis limits using my dataset min/max, then loop through the data and get RGB values for every point, that I could then use for the scatter plot.
Anyone know of any function that exists to do this?

See my answer here: http://www.mathworks.com/matlabcentral/answers/16644-rgb-colour-pixel-plot
I did make my own MATLAB-only 3D color gamut scatterplot but it's very slow and not as good as the ImageJ version. If you really want that, let me know.
