How do I know the length from the center of the object to the vertical axis edge and the horizontal axis edge?

Here's a picture of the pill, you can see that it's not a circle. I want to know the length from the center to the vertical axis edge and the horizontal axis edge

You can do something along these lines, where the location of the centroids seems like what you want:
I = imread('image.jpeg');
Ibw = im2bw(I);
Ilabel = bwlabel(Ibw);
stat = regionprops(Ilabel,'centroid');
imshow(I);
hold on;
for i = 1:numel(stat)
plot(stat(i).Centroid(1), stat(i).Centroid(2), 'ro');
stat(i)
end
ans = struct with fields:
Centroid: [961.5471 479.7054]
ans = struct with fields:
Centroid: [956.8800 409.4163]
ans = struct with fields:
Centroid: [951 63]
ans = struct with fields:
Centroid: [997 448]

Or
xyCentroids = vertcat(stats); % N by 2 array. x in column 1, y in column 2
% Or if you want them in separate vectors:
xCentroids = xyCentroids(:, 1);
yCentroids = xyCentroids(:, 2);
