Key Points

  • The ICDAR 2025 Competition focuses on advancing Document Image Machine Translation (DIMT), which translates text in document images by integrating both textual content and complex page layout analysis.
  • The competition features two main tracks—OCR-free and OCR-based—each divided into small and large model subtasks, encouraging innovation with models of varying sizes.
  • The challenge attracted significant participation with 69 teams and 27 valid submissions, demonstrating growing interest and engagement in multimodal document understanding.
  • Analysis of results indicates that large-model approaches are particularly effective, establishing a promising new paradigm for handling complex-layout document image translation.
  • The competition report covers motivations, dataset construction, task definitions, evaluation protocols, and results, providing valuable insights and highlighting opportunities for future research in this emerging area.

Abstract:Document Image Machine Translation (DIMT) seeks to translate text embedded in document images from one language to another by jointly modeling both textual content and page layout, bridging optical character recognition (OCR) and natural language processing (NLP). The DIMT 2025 Challenge advances research on end-to-end document image translation, a rapidly evolving area within multimodal document understanding. The competition features two tracks, OCR-free and OCR-based, each with two subtasks for small (less than 1B parameters) and large (greater than 1B parameters) models. Participants submit a single unified DIMT system, with the option to incorporate provided OCR transcripts. Running from December 10, 2024 to April 20, 2025, the competition attracted 69 teams and 27 valid submissions in total. Track 1 had 34 teams and 13 valid submissions, while Track 2 had 35 teams and 14 valid submissions. In this report, we present the challenge motivation, dataset construction, task definitions, evaluation protocol, and a summary of results. Our analysis shows that large-model approaches establish a promising new paradigm for translating complex-layout document images and highlight substantial opportunities for future research.
