Please examine this photograph of an Imperial I-class Star Destroyer and tell us, using information only from the image, how long the Star Destroyer is? How large was it in the first Star Wars film?

Ran in:
filename = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/1379339/image.png';
grey = rgb2gray(imread(filename));
BW = grey >= 250;
imshow(BW)
props = regionprops(BW, 'MajorAxisLength');
object_size = props.MajorAxisLength %in pixels
object_size = 640.1314
