TL;DR

What is an object detection model?

An object detection model is a deep learning architecture that classifies and localizes target objects within an image or video frame. While standard image classifiers assign a single label to an entire scene, an object detection model outputs localized predictions. These predictions consist of bounding box coordinates, class labels, and confidence scores for every detected object instance

What are the main families of object detection models?

Object detection models broadly fall into two families. Two-stage detectors like R-CNN, Fast R-CNN, Faster R-CNN, Mask R-CNN, first propose candidate regions and then classify them, trading speed for high accuracy. One-stage detectors like YOLO series, SSD, RetinaNet, EfficientDet, skip the proposal step and predict boxes and classes in a single forward pass, achieving real-time speeds with competitive accuracy.

What is the difference between YOLO and Faster R-CNN?

Faster R-CNN is a two-stage detector that relies on a Region Proposal Network to isolate candidate bounding boxes. This architecture provides high…
