Feature space transforms for Czech sign-language recognition
Jan Trmal, Marek Hrúz, Jan Zelinka, Pavel Campr, Luděk Müller, Luděk Müller · 2008
In this paper we describe a HMM-based sign language recognition (SLR) system for isolated signs. In the first part we describe the image parametrization method producing features used for recognition. Our goal was to find the best combination of a feature space dimension reduction method and an HMM structure.
