Object Detection

Object detection has evolved from hand-crafted features (HOG + SVM) through two-stage detectors (Faster R-CNN) to single-stage architectures (YOLO, SSD) and most recently to end-to-end detection transformers (DETR, RT-DETR).

Detection transformers remove the need for hand-tuned components like non-maximum suppression (NMS) and anchor boxes. They use a set-based loss (Hungarian matching) to directly predict a fixed set of detections in parallel. RT-DETR (Real-Time Detection Transformer) achieves YOLO-level speed with superior accuracy and is fully open-source under Apache 2.0.

In production, object detection models must handle diverse conditions: varying lighting, camera angles, partial occlusion, and class imbalance. Deployment considerations include model quantisation (INT8, FP16), batch inference, and integration with tracking systems for video applications.

Datameister deploys detection transformers for real-time applications in sports analytics, industrial inspection, and autonomous systems - typically as the first stage of a larger visual intelligence pipeline.
