Fine-Tuning Object Detection: Anchor Boxes & Assignment Strategies
Taming the Detectives: Understanding Anchor Boxes and Their Assignment Strategies Object detection, the art of identifying and localizing objects within images, is a cornerstone of computer vision. While there are many approaches to this problem, one crucial element stands out: anchor boxes. These predefined bounding boxes act as starting points for our object detectors, guiding them towards the true target locations. But how do we choose these anchor boxes effectively? That's where anchor box assignment strategies come into play. Think of anchor boxes like potential homes for our objects. We need to place these "homes" strategically so that they have a high chance of overlapping with the actual object boundaries. This is where two powerful techniques, K-means clustering and grid...
