Call for Participation: ICDAR 2019 CROHME + TFD Competition (repost)

The 6th Competition on Recognition of Handwritten Mathematical Expressions (CROHME) and Typeset Formula Detection (TFD) will be organized in conjunction with ICDAR 2019.

Important Dates

Feb 28, 2019  Release of training set
Mar 15, 2019  Registration deadline
Apr  1, 2019  Release of test set
Apr 30, 2019  Result submission due
May 15, 2019  Initial submission of competition reports

During its history, the CROHME competition has become the standard benchmark for comparing online handwritten math recognition systems. An IJDAR paper summarizing the systems and findings from the first four years of the competition is available, along with publications summarizing the outcome of each competition in ICFHR and ICDAR (2011-2014, 2016). Currently, the CROHME dataset is used by research groups from around the world.

This new instance of the CROHME competition will have three main tasks. As in previous CROHMEs, the first task concerns the recognition of isolated handwritten formulas. There will be a new task for offline handwritten formula recognition from images. Finally, we will have a new task for detecting formulas in document pages.

Task Overview

1.) Online handwritten formula recognition: Expression recognition from strokes. Subtasks:

    1. Isolated math symbol recognition
    1. Parsing expressions from valid symbol locations and labels

2.) Offline handwritten formula recognition: Expression recognition from images. Subtasks:

    1. Isolated math symbol recognition
    1. Parsing expressions from valid symbol locations and labels

3.) Detection of formulas in document pages. Subtasks:

    1. From raw images of document pages
    1. From provided symbol locations and labels

Subtasks 1-a)/2-a) and 1-b)/2-b) are provided to observe the behavior of symbol recognition and relationship parsing in isolation, without the additional complexity of symbol segmentation and recognition.

Awards. Awards will be provided for each of the main tasks, based on expression and detection rates.

Data and Submission

The CROHME organizers will provide an expanded training set, along with a new test set. Participants are welcome to enhance/expand the provided training data, or use additional data for their systems. Submissions will be made using an online system: recognition results will be uploaded through the site, and then the leaderboard will be updated automatically.

Call for Participation: ICDAR 2019 SROIE Competition

The Competition on Scanned Receipts OCR and Information Extraction (SROIE) will be organized in conjunction with ICDAR 2019.

Important Dates

Mar 01, 2019  Training/validation set available
Mar 31, 2019  Registration deadline
Apr 15, 2019  Submission open
Apr 30, 2019  Deadline for competition participants

Scanned receipts OCR and information extraction (SROIE) are the processes of recognizing and extracting key texts from scanned receipts and invoices. SROIE can provide services for many applications, such as efficient archiving, fast indexing and document analytics, therefore playing critical roles in streamlining document-intensive processes and office automation in many financial, accounting and taxation areas. However, SROIE also faces big challenges, such as very high accuracy requirements and low receipt quality. In recognition of the above challenges, importance and huge commercial potentials of SROIE, this ICDAR 2019 competition on SROIE is proposed. We welcome participation from interested parties, aiming to draw attention from the OCR and DAR communities and promote research and development on SROIE. This competition uses the Robust Reading Competition Web portal for organization and management.

Dataset and Tasks The proposed competition will develop well-annotated receipt dataset with 1000 whole scanned receipt images. Each receipt image has four key text fields of interests, such as goods name, unit price and total cost. There are two specific competition tasks in this competition: scanned receipt OCR and key information extraction. Compared to the other widely studied OCR tasks of ICDAR, receipt OCR is a much less studied problem and has some unique challenges. On the other hand, research works on extraction of key information from receipts have been rarely published.

Task One: Scanned Receipt OCR

The aim of this task is to accurately localize texts with 4 vertices and recognize the text in the localized bounding boxes. The text localization ground truth will be at least in the level of words. As participating teams may apply localization algorithms to locate text at different levels (e.g. text lines), the methodology based on DetVal will be implemented for the evaluation of text localizazation in this task.

Task Two: Key Information Extraction

The aim of this task is to extract texts of a number of key fields from scanned receipts. For each test receipt image, the extracted texts are compared to the ground truth. An extract text is marked as correct if both submitted content and category of the extracted text match the groundtruth. The mAP is computed over all the extracted texts of the test receipt images. F1 score is computed based on the mAP and recall. F1 score is used for ranking.

Pattern Recognition Letters Special Issue on DLVTA: Deep Learning for Video Text Analysis (repost)

Important Dates:

Feb 1 - Feb 28, 2019   Paper Submission Period 

We are living in a world where we are seamlessly surrounded by multimedia content: text, image, audio, video etc. Much of it is due to the advancement in multimodal sensor technology. For example, intelligent video-capturing devices capture data about how we live and what we do, using surveillance and action cameras as well as smart phones. These enable us to record videos at an unprecedented scale and pace, embedded with exceedingly rich information and knowledge. Now the challenge is to mine such massive visual data to obtain valuable insight about what is happening in the world. Due to the remarkable successes of deep learning techniques, new research initiates are taken to boost video analysis performance significantly.

Deep learning is a new field of machine learning research, to design models and learning algorithms for deep neural networks. Due to the ability of learning from big data and the superior representation and prediction performance, deep learning has gained great successes in various applications of pattern recognition and artificial intelligence, including video processing, character and text recognition, image segmentation, object detection and recognition, face recognition, traffic sign recognition, speech recognition, machine translation, to name a few.

Deep video analytics, or video text analytics with deep learning, is becoming an emerging research area in the field of pattern recognition. It is important to understand the opportunities and challenges emerging in video text analysis with deep learning techniques, identify key tasks and evaluate the state of the art, showcase innovative methodologies and ideas, introduce large scale real systems or applications, as well as propose new real-world datasets and discuss future directions. This virtual special issue will offer a coordinated collection of research updates in the broad fields ranging from computer vision, multimedia, text processing to machine learning. We solicit original research and survey papers addressing the synergy of video understanding, text analysis and deep learning techniques. The topics of interest include, but are not limited to:

  • Deep learning for video text segmentation
  • Deep learning for video text analysis
  • Deep learning for character and text recognition in video
  • Deep learning for scene text detection and recognition
  • Deep learning for text retrieval from video
  • Deep learning for graphics and symbol recognition in video
  • Video categorization based on text
  • Deep learning for other CBDAR tasks, etc.

Pattern Recognition Special Issue on Scene Text Reading and its Applications (STRA) (repost)

Important Dates:

Feb 15 - Mar 31, 2019   Paper Submission Period 

Text in scenes is an important source of information, since it conveys high-level semantics and is almost seen everywhere. These unique traits make scene text reading, involving automated detection and recognition of texts in scene images and videos, a very active research topic in the communities of computer vision, pattern recognition, and multimedia. Recently, these communities have observed a significant surge of research interests and efforts regarding the topic of Scene Text Reading, which is evidenced by the huge number of participants and submissions of ICDAR competitions as well as papers published on top journals and conferences.

Meanwhile, various real-world applications, such as product search, augmented reality, video indexing and autonomous driving, have formed strong demands for technique and systems that can effectively and efficiently extract and understand textual information in scene images and videos. This special issue will feature original research papers related to the theories, ideas, algorithms and systems for Scene Text Reading, together with applications to real-world problems.

The topics of interest include (but not limited to) the following:

  • Basic theories and representations regarding text in natural scenes
  • Scene text detection methods for scene images
  • Scene text recognition methods for scene images
  • End-to-end reading systems for scene images
  • Text detection and recognition in born-digital images
  • Text detection, recognition and tracking in videos
  • Script identification in the wild
  • Text information mining from web images and videos
  • Quality assessment and text image/video restoration methods
  • Benchmark datasets and performance evaluation methods

Pattern Recognition Letters Special Issue on Hierarchical Representations: New Results and Challenges for Image Analysis

Important Dates:

May 1 - May 31, 2019   Paper Submission Period 

Image representations based on hierarchical, scale-space models and other non-regular / irregular grids have become increasingly popular in image processing and computer vision over the past decades. Indeed, they allow a modeling of image contents at different (and complementary) levels of scales, resolutions and semantics. Methods based on such image representations have been able to tackle various complex challenges such as multi-scale image segmentation, image filtering, object detection, recognition, and more recently image characterization and understanding, potentially involving higher level of semantics.

The proposed virtual special issue will consider extended and updated versions of papers published at the recent ICPRAI 2018 conference as well as submissions from anybody proposing innovative methods in the field of image representation with emphasis, but not restricted to computer vision and image processing, medical imaging, 2D and 3D images, multi-modality, remote sensing image analysis, image indexation and understanding.


The main topics of this HIERARCHY virtual special issue include, but are not limited to:

  • image decomposition on the basis of frequency spaces (Fourier, wavelets, etc.)
  • hierarchies linked to the image space, mathematical morphology, connected operators
  • scale-space representations
  • non-regular / irregular grid image representations
  • multi-scale representation in computer-vision
  • evaluation of hierarchical image representations

The aim of this special issue is to popularize the use of hierarchical methods in image processing and analysis. Indeed, although these methods have become very popular in computer vision over the last 20 years, their potential impact is largely underexploited in image processing and analysis.


The review process will follow the standard PRLetters scheme. In particular, each paper will be reviewed by two referees. The referees will include the program committee members of the special session at ICPRAI 2018 on the same topic and other invited referees selected from the EES.

This is an open call-for-papers from outside the ICPRAI 2018 conference, though participants of the virtual special session on hierarchical representations of images will be invited to submit an extended article of their contribution. These articles must include at least 30% of new contribution (theoretical or experimental results), with different figures and a different title than the one of the ICPRAI paper. The common content between the ICPRAI paper and the HIERARCHY article cannot be exactly the same. This virtual special issue also accepts totally new proposals; both types of submissions must respect the following guidelines.

All submissions have to be prepared according to the Guide for Authors as published in the Journal Web Site at:

The authors are invited to upload their article through http://ees.elsevier.com/prletters/ during the submission period (see above), by indicating the virtual special issue acronym (HIERARCHY). Their contribution should not have been published previously, or not be under revision for any other publication elsewhere. In the case of an extension of ICPRAI session, the original work must be attached, and a description of major changes must be provided. Guest editors will judge the suitability and scope of each contribution.

All submitted papers will be reviewed according to the guidelines and standards of PRLetters. At least two (2) reviewers will be assigned, and 2 reviewing rounds can occur for each submitted article. The maximal length is 7 pages, except for articles requiring major revision and additional content by the reviewers, for which the maximal length can be extended to 8 pages. If an article still need major revision after the second round, it will be rejected.

Only original, high-quality, technically sound articles and in-line with the PRLetters standard guidelines, will be considered for publication in this virtual special issue. Submissions will be judged by their contributions to the virtual special issue topics, clarity of presentation, potential impact to the field, and suitability to publication in an archival journal.

Description (taken from the Foreward by Jean-Marc Ogier):

The book starts with a clear and concise overview of document image analysis; the author puts a position about where does graphics processing lie (Chap. 1), which is immediately followed by graphics recognition (Chap. 2) in detail. The best part of the book is it summarizes the rich state-of-the-art techniques in addition to those international contests that have been happening in every 2 years since the 90s. This summary helps readers understand the scope and importance of graphics recognition in the domain. Another important issue is the author framed the need for validation protocol (Chap. 3) so that it allows a fair comparison that let us review our advancements then and now. Three different fundamental approaches, viz. statistical (Chap. 4), structural (Chap. 5), and syntactic (Chap. 7), are comprehensively described for graphics recognition by taking state-of-the-art (up to date) research techniques in addition to the hybrid approaches (Chap. 6). For a complex graphics recognition problem, structural approaches are found to be appropriate and have been well covered in the book. Interestingly, even though there exist a few works on the syntactic approach for graphical symbol recognition, the author sets a position and its importance as the image description happens to be close to human understanding language. The summary of the book (Chap. 8) is succinct and to the point […] I strongly believe the book has the potential to attract a large audience.
