Aspect Ratios: Shaping Object Detection with Anchors

The Unsung Heroes of Object Detection: How Anchor Box Aspect Ratios Shape Your Vision Imagine teaching a computer to see the world like humans do. It's a complex task, requiring the ability to recognize and locate objects of varying shapes and sizes within an image. One crucial component in this process is object detection, and at its heart lies a fascinating concept called anchor boxes. Anchor boxes are essentially pre-defined regions in an image, acting as templates for potential object locations. They come in various shapes and sizes, determined by their aspect ratio - the ratio of width to height. Think of it like this: some anchor boxes are tall and thin like a person standing, others are wide like...

Anchor Ratios: Tuning Object Detection Precision

The Unsung Hero: How Anchor Box Aspect Ratios Shape Object Detection Accuracy Object detection, the ability of machines to identify and locate objects within images or videos, is a fundamental building block in computer vision. While algorithms like YOLO and SSD have become household names, there's a less-celebrated component that plays a crucial role: anchor boxes. These pre-defined bounding boxes act as templates, guiding the detection process and influencing accuracy significantly. One often overlooked factor impacting performance is the aspect ratio of these anchor boxes. Think of anchor boxes as initial guesses for object locations. They come in various shapes and sizes, defined by their width and height ratios. A box with a 1:1 aspect ratio is square, while a...
