Description de la source

RT-DETRv2 Document Layout Detection (GGUF)

Document layout analysis model for CrispEmbed. Detects 17 region types in document images.

Architecture

  • Backbone: ResNet-50-D (BN-folded Conv2d)
  • Encoder: HybridEncoder (AIFI self-attention + FPN/PAN with CSP-RepVGG)
  • Decoder: 6-layer transformer with deformable multi-scale cross-attention (300 queries)
  • Classes: 17 (text, title, table, figure, formula, caption, section_header, list_item, footnote, page_header, page_footer, code, document_index, checkbox_selected, checkbox_unselected, form, key_value_region)
  • Parameters: 42M
  • Source: docling-project/docling-layout-heron (Apache-2.0)

Usage

# CLI
./build/crispembed -m layout-heron --layout document.png --json

# Server
./build/crispembed-server --layout layout-heron-q8_0.gguf
curl -X POST http://localhost:8080/layout/detect -d '{"image": "page.png"}'

from crispembed import CrispLayout
layout = CrispLayout("layout-heron-q8_0.gguf")
regions = layout.detect("document.png")

Parity

  • Encoder: all stages cos=1.0 vs HF reference (with exact input)
  • Detection score: 0.934 (HF reference: 0.955)
  • 14 parity bugs found and fixed via systematic layer-by-layer diff

Provenance and EU AI Act Art. 53 note

  • Upstream model: docling-project/docling-layout-heron — published by docling-project.
  • Upstream licence: apache-2.0. This repository redistributes under the same terms; it grants no rights the upstream licence does not.
  • What was done here: format conversion and/or quantisation only (GGUF). No training, no fine-tuning, no merging, no distillation, no change to architecture, vocabulary or capability. Only the numeric representation of the upstream weights differs.
  • Training data: documented — where it is documented at all — by the upstream provider; see the upstream model card. No training data was used, added or selected by this repository.
  • Provider status: under Regulation (EU) 2024/1689 the upstream authors remain the provider of this model. Converting the serialisation format does not make this repository the provider of a new general-purpose AI model, and no such claim is made. Questions about training content, copyright policy or model capability belong upstream.
