Which object detection algorithm is best?

There is no universal best detector. Choose the model that passes severe-error, latency, memory, licence and deployment gates on representative data and target hardware.

Is YOLO always faster than Faster R-CNN?

YOLO-style models often target real-time inference, while Faster R-CNN uses a two-stage pipeline, but exact speed depends on model size, runtime, hardware, precision, batch size and the complete application path.

What is the difference between one-stage and two-stage detection?

One-stage detectors predict classes and boxes densely in one main pass. Two-stage detectors first propose candidate regions and then classify and refine them. Modern performance overlaps, so architecture is only one selection factor.

What is an anchor-free detector?

An anchor-free detector predicts objects without a predefined grid of anchor-box shapes. It removes some design choices but still requires label assignment, feature-scale, threshold and post-processing decisions.

Does DETR require non-maximum suppression?

The original DETR formulation uses set prediction and bipartite matching to produce unique predictions without the conventional non-maximum-suppression stage. Individual derivatives should still be checked for their actual inference pipeline.

Should published AP and FPS values be compared directly?

Only when dataset, split, metric, input, hardware, precision, batch size and timing boundaries are equivalent. Otherwise benchmark the models again through one controlled harness.

How many models should a team benchmark?

A focused shortlist of three to five candidates is usually more useful than a broad leaderboard: include a real-time candidate, a mature reference and an architecturally different challenger.

Which metrics matter beyond mAP?

Use per-class precision and recall, severe-error counts, size and condition slices, threshold curves, calibration, p95 latency, throughput, memory, energy and operating cost.

Can a public dataset prove production readiness?

No. It supports reproducible research comparison but cannot represent every production camera, population, environment, class definition or error cost.

When should the selected detector be re-evaluated?

Re-evaluate after material data, camera, class, hardware, runtime, supplier or policy changes, and whenever monitoring detects drift or an unacceptable error pattern.
