IAM (IAM Handwriting)

Introduced in The IAM-database: an English sentence database for offline handwriting recognition20 Feb 2018 archive 2025-07-28

The IAM database contains 13,353 images of handwritten lines of text created by 657 writers. The texts those writers transcribed are from the Lancaster-Oslo/Bergen Corpus of British English. It includes contributions from 657 writers making a total of 1,539 handwritten pages comprising of 115,320 words and is categorized as part of modern collection. The database is labeled at the sentence, line, and word levels.

11 shown of 11 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 198. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
