چکیده

The gesture recognition process, in general, may be divided into two stages: motion sensing, which extracts useful data from hand motion; and the classification process, which classifies the motion sensing data as gestures. We have developed the visionbased Hand Motion Understanding (HMU) system that recognises static and dynamic Australian Sign Language (Auslan) signs by extracting and classifying 3D hand configuration data from the visual input. The HMU system uses a combination of a 3D hand tracker for motion sensing, and an adaptive fuzzy expert system for classification. This paper explains the 3D hand tracker that extracts the changes in the 21 degrees-of-freedom parameters of the hand from a sequence of images. The tracker performance is successfully demonstrated by tracking the hand motions appearing in Auslan sign sequences.

Visual Sign Language Recognition

We have developed the Hand Motion Understanding (HMU) system that understands static and dynamic signs of the Australian Sign Language (Auslan). The HMU system uses a visual 3D hand tracker for motion sensing, and an adaptive fuzzy expert system for classification of the signs. This paper presents the hand tracker that extracts 3D hand configuration data with 21 degrees-of-freedom (DOFs) from a...

Adaptive Fuzzy Expert System for Sign Recognition

The Hand Motion Understanding (HMU) system is a vision-based Australian sign language recognition system that recognises static and dynamic hand signs. It uses a visual hand tracker to extract 3D hand configuration data from a visual motion sequence, and a classifier that recognises the changes of these 3D kinematic data as a sign. This paper presents the HMU classifier that uses an adaptive fu...

An Adaptive Fuzzy Expert System for 3D Hand Motion Understanding

The Hand Motion Understanding (HMU) system recognises static and dynamic hand signs in Australian Sign Language (Auslan) by dealing with "fine grain" hand motion, such as configuration changes of fingers. The system consists of the 3D hand tracker and the adaptive fuzzy expert classifier. The hand tracker extracts 3D hand configuration data with 21 degrees-of-freedom (DOFs) from a visual motion...

Sign Language Recognition with the Kinect Sensor Based on Conditional Random Fields

Sign language is a visual language used by deaf people. One difficulty of sign language recognition is that sign instances of vary in both motion and shape in three-dimensional (3D) space. In this research, we use 3D depth information from hand motions, generated from Microsoft's Kinect sensor and apply a hierarchical conditional random field (CRF) that recognizes hand signs from the hand motio...

Persian sign language detection based on normalized depth image information

There are many reports of using the Kinect to detect hand and finger gestures after release of device by Microsoft. The depth information is mostly used to separate the hand image in the two-dimension of RGB domain. This paper proposes a method in which the depth information plays a more dominant role. Using a threshold in depth space first the hand template is extracted. Then in 3D domain the ...
