**TLDR:** An architectural design that combines visual information across scales to improve multi-scale object understanding.

<p>Feature Pyramid Networks were developed to combine information across multiple resolution levels, especially for detection and segmentation tasks. Small objects may be more visible at fine resolution, while larger structures become clearer in more abstract layers. This makes multi-scale representation fusion essential. FPN designs have contributed significantly to modern visual perception systems.</p>
