Realization for Finger Character Recognition Method by Similarity Measure of Finger Features

Abstract

In this paper, we present a novel finger character recognition method in sign language using dimension reduction finger character feature knowledge base for similarity measure. A sign language communication is crucial method for deaf or hearing-impaired people. One of the most important problems is that very few people can understand a sign language. Essentially, there is not enough image data set for finger character learning. In addition to aligning a corpus of images of finger character, it is necessary to realize an automatic recognition system for finger characters in a sign language. We construct a knowledge base for finger character features and apply it to realize a novel finger character recognition. Our method enables finger character recognition by similarity measure between the input finger character features and a knowledge base. The experimental results show that our approach efficiently utilizes the knowledge base generated from a small amount of finger character images. We also present our prototype system and experimental evaluation.
