Call for Papers HIP’21 – 6th International Workshop on Historical Document Imaging and Processing

Impact Centre of CompetenceEvents, HIP21, News

Dates: September 5-6, 2021

Venue: Lausanne, Switzerland / online



The HIP’21 workshop is co-located with the ICDAR2021 Conference in Lausanne, Switzerland. HIP brings together researchers working with historical documents and intends to be complementary and synergistic to the work in analysis and recognition featured in the main sessions of ICDAR, the premier international forum for researchers and practitioners in the document analysis community.
Workshop topics include (but are not limited to):

  • Imaging and Image Acquisition
  • Imaging for fragile materials
  • Multispectral imaging
  • Hyperspectral imaging
  • X-Ray Fluorescence imaging
  • 3D imaging
  • Camera-based/non-invasive acquisition
  • Case studies/applications
  • Digital Archiving Considerations
  • Compression issues
  • Measuring essential resolution (colour, spatial) and metadata
  • Modelling of document image degradation
  • Historical Collections
  • Military records, personal journals, church records, medieval manuscripts, etc.
  • Scientific, technical and educational documents
  • Government archives, documents from the world cultural heritage, multi-language
  • Document Restoration/Improving readability
  • Removing or minimizing damages, defects, ink-bleed
  • Completing and filling in missing pieces based on context, prior knowledge
  • Machine-learning algorithms for enhancement based on example images
  • Interactive tools from a user viewpoint
  • Learning from user-directed image enhancement
  • Information Extraction (within the context of historical documents)
  • Content-based retrieval
  • Automated or semi-automated transcription
  • Machine-learning algorithms for content extraction, including recurrent neural networks, auto-encoders, and unsupervised feature learning
  • Content recognition based on surrounding and supporting context
  • Ontologies for modelling historical document content
  • Family History Documents and Genealogies
  • Personal, Family, National and Historical Collections of Family Genealogy and Histories
  • Extracting and linking names, dates, places, etc.
  • Extracting, linking and piecing together personal and family histories and narratives
  • Discovering historical social networks
  • Automated Classification, Grouping and Hyperlinking of Historical Documents
  • Style identification (of printed text, dating or author identification)*
  • Searching for Documents over the Internet
  • Web-based navigation within/among document images
  • Search/query, retrieval, summarization or condensation of document images
  • Document collecting, clustering, linking and analysis technologies
  • Parallel tagging of images, transcripts, and other document layers
  • Digital Humanities applications of document analysis and recognition
  • Computer Vision for Computational History
  • Digital methods and tools for the study of historical documents
  • Computational access to historical documents (e.g. Juypter notebooks)
  • Workflows and pipelines for document analysis and recognition
  • Crowdsourcing

* For work focusing on handwriting/paleography, we recommend you have a look at IWCP2021.

Submission instructions and publication

Submissions must not exceed 6 pages in length. It is not required to anonymize the submission, but authors are welcome to do so if they prefer it.
Submissions should be written in English and must be formatted according to the current ACM SIGConference Proceedings Template. Note that ACM has created a new LaTeX template and updated the existing Word templates. Authors also need to apply the ACM Computing Classification System (CCS)according to the ACM SIG Conference Proceedings Template.
Papers should be submitted as PDF documents via the Easychair conference management system:
At least one author of each accepted paper must register to the workshop and present the paper.
Accepted papers will be published in the ACM Digital Library (see also the Proceedings of previouseditions, e.g. of 2019, 2017).

Important dates (Time zone: Anywhere on Earth):

  • Submission Deadline: May 17, 2021
  • Acceptance Notification: June 28, 2021
  • Camera Ready: July 12, 2021
  • Workshop: September 5-6, 2021


We are hopeful that it will be possible – at least for some – to convene in Lausanne inSeptember, but rest assured that options for remote participation will be available either way.

Program committee:


  • Apostolos Antonacopoulos (General Chair)
  • William Barrett (Honorary Chair)
