Can I use regionprops two times with two different variables in the same program at time?

if true
clc;
close all;
clear;
workspace;
folder = pwd;
% folder = pwd;
filepattern = fullfile(folder, '*.png');
srcFiles = dir(filepattern);
numImages = length(srcFiles);
for k = 1 : numImages
fullFileName = fullfile(folder, srcFiles(k).name);
a = imread(fullFileName);
bwimg =bwareafilt(~a, 1);
s=regionprops(bwimg,'Orientation');
theta = s(1).Orientation;
if theta>=0 && theta<90
phi=90-theta;
Y=imrotate(bwimg,phi);
else
phi=90+theta;
Y=imrotate(bwimg,-phi);
end
s1=regionprops(Y,'Centroid','BoundingBox','MajorAxisLength','MinorAxisLength');
circleCenterX = s1.Centroid(1);
circleCenterY= s1.Centroid(2);
diameters = mean([s1.MajorAxisLength s1.MinorAxisLength],2);
end
end
This is showing me error that multiple field reference. I am first rotating the images then again taking its property as centroid and orientation has been changed from the original image but its not working.

Have you checked this code with the single image file (remove loop)?

You need to show that error to us, too.

Probably following lines have error.
circleCenterX = s1.Centroid(1); circleCenterY= s1.Centroid(2);
s1 might be nx1 struct with n greater than 1. My guess is bwareafilt is producing an oversegmented object. You can try the following:
Area = [s1.Area];
index = find(Area==max(Area));
circleCenterX = s1(index).Centroid(1);
circleCenterY= s1(index).Centroid(2);
diameters = mean([s1(index).MajorAxisLength s1(index).MinorAxisLength],2);

I'm not sure what's happening there. regionprops should not return 2x1 struct without any values. If image was empty, it should have returned an empty struct (0x1).

Yaa this is happening.For few images I am getting only 2×1 struct only. If I use imcomplement instead of bwareafilt then also I am getting the same thing
