Abstract(in English) | In sign language recognition system, there are two main methods for capturing hands movement from signers. The first one is generally called the motion capture method which uses special sensors (e.g. CyberGlove[○!R]) capture the movement of the signer. The second one, which is called image-based approach relies on videos of signers to capture signs. In this paper, We adopt the second approach. While image-based approach has some advantages against sensor-based approach, it is difficult to overcome occlusion problems. Hidden Markov Model (HMM) have been widely used in sign language recognition. Also, in the field on speech recognition and speech synthesis, HMM have been used for acoustic modeling. In speech synthesis domain, Multi-space probability HMM (MSD-HMM) have been proposed as an extension of HMM that includes discrete and continuous HMM. We adopt MSD-HMM technique in order to overcome occlusion problems. This paper describes to use multi-space probability distribution (MSD) to model occluded hand positions jointly with visible hand positions. Experimental result obtained in Japanese sign language recognition indicate MSD provided almost equal to word recognition accuracy across conventional HMM method using interpolated trajectory of hand positions. |
