Refining Object Detection: Anchor Boxes and Aspect Ratios
Anchors: The Secret Weapon of Object Detection - Understanding Aspect Ratios Object detection, the ability for computers to identify and locate objects within images or videos, is a cornerstone of modern AI. From self-driving cars navigating busy streets to medical imaging diagnosing diseases, this technology powers countless applications. But behind the scenes lies a crucial component often overlooked: anchor boxes. These small bounding boxes are pre-defined at various locations and scales across an image. They serve as the initial guesses for where objects might exist. Think of them like search grids laid out across the scene, helping the algorithm quickly pinpoint potential object locations. Enter Aspect Ratios: Refining the Search While anchor boxes provide a starting point, simply using generic...
