Unofficial ONNX conversion of Roboflow RF-DETR — small

Single-file ONNX exporting the raw model outputs (no NMS, no sigmoid, no top-k, no resizing — all pre/postprocessing stays outside the graph). Unofficial conversion; not endorsed by the upstream authors. Upstream-reported COCO AP: 53.0 (not re-measured here).

Class table is UNVERIFIED. RF-DETR emits a 91-slot DETR-family COCO layout (index 0 = background). Confirm the column count and no-object slot against this exact file (Netron + one known image) before relying on the labels.

Input contract

Preprocessing: RGB → resize (stretch) to 512×512 → float32 ÷255 → ImageNet mean/std after ÷255 → HWC→CHW → batch dim.

Output contract

91-class COCO (torchvision 91-slot), 300 queries, DETR-style set prediction — no NMS.
