Как я могу выровнять текст по центру<img> желательно с помощью FlexBox?

body {
  margin: 0px;
}

.height-100vh {
  height: 100vh;
}

.center-aligned {
  display: box;
  display: flex;
  box-align: center;
  align-items: center;
  box-pack: center;
  justify-content: center;
}

.background-image {
  position: relative;
}

.text {
  position: absolute;
}

<section class="height-100vh center-aligned">
  <img class="background-image" src="http://vignette2.wikia.nocookie.net/uncyclopedia/images/f/f8/Stand-out-in-the-crowd-300x300.jpg" />
  <div class="text">SOME TEXT</div>
</section>
