I am getting an error while running regionprops. How?

[L,N] = superpixels(I,50);% superpixels=44
props = regionprops(L,'MeanIntensity','PixelValues','PixelList','PixelIdxList');
I am getting this error."REGIONPROPS needs I as an input to calculate 'MeanIntensity'".
Thankyou

You need to pass in the original image. You can't just pass in the labeled image. If you want the mean intensity of regions in an image, of course you need to pass in the image itself. The labeled image L merely tells where the regions are in the original image. You have to pass in the image itself as the second argument if you want to measure its intensities in those regions.

If the color distance between P1 and P2 is "low", and the color distance between P2 and P3 is "low", but the color distance between P1 and P3 is not "low", then how do you want to handle the situation?

You are passing in a label matrix but asking for mean intensity. In order to do both at the same time you need to pass the intensity matrix as well. If I recall correctly you would pass it as the second argument.
