Gaze tracking and its application to video coding for sign language
نویسندگان
چکیده
Sign language communication via videotelephone has demanding visual quality requirements. In order to optimise video coding for sign language it is necessary to quantify the importance of areas of the video scene. Eye movements of deaf users are tracked whilst watching a sign language video sequence. The results indicate that the gaze tends to concentrate on the face region with occasional excursions (saccades). The implications of these results for prioritised coding of sign language video sequences are discussed.

A perceptually optimised video coding system for sign language communication at low bit rates
The ability to communicate remotely through the use of video as promised by wireless networks and already practised over fixed networks, is for deaf people as important as voice telephony is for hearing people. Sign languages are visual–spatial languages and as such demand good image quality for interaction and understanding. In this paper, we first analyse the sign language viewer’s eye-gaze, ...
متن کاملEnhancing Video Streaming Using Real-Time Gaze Tracking
While users are watching videos, they can only focus and evaluate one small part of the presented video frame which is within the focal view point. Video coding however often assumes equal distribution of attention or has predefined areas of interest, regardless of where the observer is actually looking at. In this paper, we propose a system that uses real-time information of eye gaze in order ...
متن کاملPerception of sign language and its application to visual communications for deaf people.
Video communication systems for deaf people are limited in terms of quality and performance. Analysis of visual attention mechanisms for sign language may enable optimization of video coding systems for deaf users. Eye-movement tracking experiments were conducted with profoundly deaf volunteers while watching sign language video clips. Deaf people are found to fixate mostly on the facial region...
متن کاملApplying mean shift and motion detection approaches to hand tracking in sign language
Hand gesture recognition is very important to communicate in sign language. In this paper, an effective object tracking and hand gesture recognition method is proposed. This method is combination of two well-known approaches, the mean shift and the motion detection algorithm. The mean shift algorithm can track objects based on the color, then when hand passes the face occlusion happens. Several...
