This is the code.The stats is a table, in that MajorAxisLength() and MinorAxisLength() is showing as 0*0 (double)
gray = imread('CYST RENAL-37.jpg');
grayImage = rgb2gray(gray);
level = graythresh(gray);
BW = imbinarize(gray,level);
stats = regionprops('table',BW,'Centroid',...
'MajorAxisLength','MinorAxisLength');
centers = stats.Centroid;
diameters = mean([stats.MajorAxisLength stats.MinorAxisLength],2);
radii = diameters/2;
Pls help me to solve this error. Any help is appreciated

Also I wonder if using "equivalent diameter" property would happen to be appropriate for your case.

You were trying to imbinarize() the RGB image, not the gray image.
Also, imbinarize() automatically determines the threshold by calling graythresh if you do not pass in a level.
