Abstract
Deaf, Hard-Of-Hearing and Speech-Impaired (D-HOH-SI) individuals have a specific interest in the development of affordable high-quality videoconferencing as a means of communicating with their family members and peers using sign language. Unlike Video Relay Service, which is intended to support communication between a caller using sign language and another party using spoken language, videoconferencing can directly be used either between two deaf signers or between a caller using sign language and the other using spoken language without the need of an interpreter. This paper proposes a Bandwidth Aware Gesture Based Layered (BAGBL) framework for sign language recognition based video conferencing application. Assuming a D-HOH-SI individual at the sender side, the proposed framework uses shape energy trajectory of hand sign gesture for video layering, aMulti-dimensionalMultiplechoice Knapsack Problem (MMKP) based gradational hull pareto minimization heuristic called MMKP based Pareto Minimization Heuristic for Substream Scaling (MPMHSS) and a heuristic for substream scheduling which is based on Dynamic Multilevel Priority (DMP) called Modified DMP packet scheduling (MDMP) mechanism. At the receiving side, our framework includes an automatic sign language recognizer to recognize the sign language gesture and a speech synthesizer to convert the recognized words to speech. Our framework intelligently forms and selects video layers from a video sequence to maximize the video quality. Using extensive simulation and mathematical analysis we show that the proposed solution: (i) is efficient in terms of recognition rate (ii) achieves high radio resource utilization, (iii) maximizes the received video quality.
