Image processing- how to check which Star is closer and which Star is farther in a space image : <p>Let's say we pick an image of space. Let's assume there is big star at 40 light years away and a smaller star 20 light years away. But when we look at the image both would look same size. How can we identify which is bigger and which is smaller by size and how far is it from us.</p>

<p>I want to do image processing on these images.</p>

<p>Keywords: Astronomy, space telescope, stars machine learning, opencv, python.</p>
