The online and offline Chinese handwriting databases, CASIA-OLHWDB and CASIA-HWDB, were built by the National Laboratory of Pattern Recognition (NLPR), Institute of Automation of Chinese Academy of Sciences (CASIA). The handwritten samples were produced by 1,020 writers using Anoto pen on papers, such that both online and offline data were obtained. The samples include both isolated characters and handwritten texts (continuous scripts). We collected data from writers from 2007 to 2010, and completed the segmentation and annotation in 2010. The databases include six datasets of online data and six datasets of offline data, in each case, three for isolated characters (DB1.0–1.2) and three for handwritten texts (DB2.0–2.2). In either online or offline case, the datasets of isolated characters contain about 3.9 million samples of 7,356 classes (7,185 Chinese characters and 171 symbols), and the datasets of handwritten texts contain about 5,090 pages and 1.35 million character samples. All the data has been segmented and annotated at character level, and each dataset is partitioned into standard training and test subsets.
