ICDAR 2026 Competition on Writer and Pen Identification from Hand-Drawn Circles
We’re hosting CircleID, the ICDAR 2026 competition on learning subtle details in hand-drawn circles from scanned images. The challenge features two tracks: Writer Identification and Pen Classification. CircleID includes an out-of-distribution twist for Writer Identification: The test set contains circles from writers not seen during training, so methods must learn to recognize unknown writers.

ICDAR 2025 Competition on Glyph Detection in 15th-Century European Printed Documents
This competition is focused on the detection of glyphs in early European printed documents from the 15th century. The primary aim is to build an extensive corpus of glyphs by accurately extracting a large number of characters, with an emphasis on high precision rather than complete coverage. We will provide dataset that contains multiple historical […]

ICDAR 2021 Competition on Historical Document Classification
This competition investigates the performance of historical document classification. The analysis of historical documents is a difficult challenge commonly solved by trained humanists. We provide three different classification tasks, which can be solved individually or jointly: font group, location, date. Additionally, we will declare an overall winner for participants who contributed to all three tasks. […]This competition investigates the performance of historical document classification.
