This paper presents a lexical post-processing optimization for handwritten word recognition. The aim of this work is to explore the combination of different lexical postprocessing approaches in order to optimize the recognition rate, the recognition time and memory requirements. The present method focuses on the following tasks: a lexicon organization with word filtering, based on holistic word features to deal with large vocabulary (creation of static sublexicon compressed in a trie

Experimental results are reported using several lexicon sizes (about 1,000; 7,000 and 25,000 entries) to evaluate different optimization strategies according to the recognition rate, computational cost and memory requirements.
