Summary
In this chapter, the state of the art of word-spotting and rejection methods is presented. After an introduction to word-spotting, available algorithms are classified in several categories. This is followed by a description of template matching word-spotting systems, garbage modeling, and the use of a large vocabulary recognizer in a word-spotting task. Then, we address the issues of vocabulary-independent word-spotting, performance measures, and rejection. The rejection problem is associated to the notion of confidence measure indicating how well an hypothesis matches with the recognized result. Consequently, confidence measures and the related problem of detecting out-of-vocabulary words are considered.
