  • Identification of Geometric Faces in Hand-Sketched 3d Objects Containing Curved-Lines
    Ahmed M.El-Sayed and A. A. Wahdan, Technology and Maritime Transport, Egypt and Aliaa A. A. Youssif, Helwan University, Egypt

    The reconstruction of 3D objects from 2D line drawings is considered as one of many important topics in the field of computer vision.The ongoing research is mainly focusing on the reconstruction of 3D objects that are mapped only from 2D straight lines, and that are symmetric in nature. Commonly, this approach only produces basic and simple shapes that are mostly flat or rather polygonized in nature, which is normally attributed to the lake of ability to handle curves. To overcome these limitations, a technique that can handle drawings that contain curves and are non-symmetric is considered. This paper discusses a novel technique that can be used to reconstruct 3D objects containing curved lines. In addition, it highlights an application that has been developed in accordance with the suggested technique that can convert a freehand sketch to a 3D shape using a mobile phone.

  • A Collaborative Coding Framework Of Rs And H.264
    Jiejun Hu and Xilong Che, Jilin University, China

    The quality of online multimedia is required higher and higher, yet the uncertainty of network is still out there. In order to ensure the quality of service in media transmission, we incorporate the erasure code and video code together and present a collaborative coding framework of RS and H.264. First of all, we analyze the common coding pattern hidden in RS and H.264. Then, we design the collaborative coding framework of the two codes. Finally, we give a prototype implementation and validate the coding effectiveness using standard dataset. The erasure data slice goes through the redundant data tunnel of H.264 thus does not involve extra traffic overhead. Experimental results show that the framework increase the quality of media transmitted.

  • Building A Text-To-Speech System For Punjabi Language
    Rupinderdeep Kaur, R.K. Sharma and Parteek Kumar,Thapar University, India

    A Text-To-Speech (TTS) system is a computer application that is capable of converting typed text into speech. This paper contains description of working of a TTS system along with architecture of the system and various available TTS systems for Indian Languages with comparison of these systems on the basis of the methods used by them for speech synthesis. TTS system generally involves two steps, text processing and speech generation. Synthetic speech may be used in several applications, like, telecommunications services, language education, aid to handicapped persons, fundamental and applied research etc. TTS involves many challenges during the process of conversion of text to speech. The most important qualities expected from speech synthesis system are naturalness and intelligibility. The general architecture of a TTS system and different waveform generation methods are discussed in this paper. A scheme for developing a TTS system for Punjabi Language is also included in this paper.

  • Multilayer Reservation and Contention Protocol for Video Streaming
    Md.Tanvir Hasan, Bangladesh University of Professionals, India and Md. Sifat Rahman, International Islamic University Chittagong, India

    Video streaming over wireless networks is compelling for many applications, and an increasing number of systems are being deployed. Video streaming of news and entertainment clips to mobile phones is now widely available. For surveillance applications, cameras can be flexibly and cheaply installed, if a wireless network provides connectivity. A wireless local area network (WLAN) might connect various audiovisual entertainment devices in a home. Last, but not least, in search and rescue operations, real time audiovisual communication over wireless adhoc networks can save lives. The need for video streaming over wireless networks mainly comes from two driving forces. First, as network service provider are racing to roll out multimedia services such as Internet Protocol Television (IPTV), one major bottleneck is in residential houses, where rewiring and truck roll costs are prohibitively high. Thus, the use of Ultra Wide Band (UWB) and Millimeter Wave (mmWAve) is highly recommended. Second, with the miniaturization of portable electronic devices, consumers demand for multimedia streams deliver to and from their handheld devices anytime and anywhere at a low cost. To reserve or not for bursty video traffic over wireless access networks has been a long debated issue. For uplink transmissions in infrastructure based wireless networks and peer - to- peer transmissions in mesh or adhoc networks, reservation can ensure the Quality-of-Service (QoS) provisioning at the cost of a lower degree of resource utilization. Contention based Medium Access Control (MAC) protocols are more flexible and efficient in sharing resources by bursty traffic to achieve.

  • Joint Kalman Channel Estimation and Turbo Equalization for MIMO OFDM Systems
    Chih-Yuan Liao, Fang-Biau Ueng, Li-Der Jeng and Yu-Kuan Chang, National Chung-Hsing University Taichung, Taiwan

    In this paper, we propose a joint Kalman channel estimation and turbo equalization for multiple-input–multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) communications over fast fading multipath channels. Error propagation can seriously affect the performance of an adaptive decision feedback equalizer (ADFE), especially when operated in inter-symbol interference (ISI) channel environments. By considering the Kalman channel estimation, this paper proposes a frequency-domain (FD) iterative soft decision feedback equalization (SDFE) scheme for the designed system. The proposed scheme combats error propagation in fast fading channel. Some simulation examples are given to demonstrate the effectiveness and comparisons of the proposed receiver.
