I can calculate mean of Tbv and Svvc using the following link.I have more images lets say Tbv2,Svvc2,RVI3,Tbv3,Svvc3,RVI3. I want to calculate the mean Tbv and Svvc of all the images at once.
Tbv1 = imread('tb.tif');
Svvc1 = imread('vv.tif');
RVI1 =imread('rvi.tif')
ME_v1 = nanmean(Tbv1( RVI1>=0 & RVI1 <=0.2));
ME_vv1 = nanmean(Svvc( RVI1>=0 & RVI1 <=0.2));
ME_v2 = nanmean(Tbv( RVI1>=0.2 & RVI1 <=0.4));
ME_vv2 = nanmean(Svvc( RVI1>=0.2 & RVI1 <=0.4));

Do your images have nans in them? I didn't know you could store tiff images if you did not have numerical data. And I didn't see any valid link in your code like you mentioned. Are your images monochrome or color? If they're monochrome, you're doing it right, but you could probably use mean() instead of nanmean().

I have some nan values in the image..but it does not matter.my question is how to calculate mean from different images...In this code I calculate mean from one image only.
