Segmentation result by k-means (k=6) clustering using the RGB color information showing the cluster group containing the eosinophils.If we refer this result to the original RGB color image (fig.7, topmost, 2nd column) we can we see that tissue structures which are not eosinophils at all were also identified as eosinophils in the result, particularly the areas indicated by arrows.
