Writer Identification and Word Spotting for the CVL Database
The CVL-database has 311 writers and was designed for writer retrieval and identification. The database consists of 7 (27 writers) respectively 5 (284 writers) different texts (101069 words at all). Additionally each page is labeled and provides the coordinates of the bounding boxes of each word (punctuations are not annotated) encoded using an XML-file. Thus, the CVL database can also be used for the evaluation of word-spotting methods. In contrast to the IAM database the number of pages of each writer is distributed more equally.
Evaluation for Writer Identification: It is suggested to use the evaluation metrics from the Writer Identification Contest (ICDAR)
