There are two examples from MathWorks that may be useful.
The first one transforms RGB to LAB. Components A and B are colors without the disturbance of light. By considering the distance between the standard colors to colors in your figure, the fruits may be separated. We may do a little change on this example, e.g. calculating histograms of colors for different fruit. See ‘. Color-Based Segmentation Using the L*a*b* Color Space’ .
The second one collects the similar colors with clus tering technology. MATLAB can automatically generate the code that you want. See Segment Image Using Auto Cluster.
