    • Distributed joint source-channel coding of video using raptor codes 
      Xu, Qian; Stankovi, Vladimir M.; Xiong, Zixiang (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2012-11-20)
      A video encoder system includes a base layer and an enhancement layer for encoding video data. The base layer encodes a reduced quality version of the video data to obtain base layer data. The enhancement layer encodes the ...
    • Layered Wyner-Ziv video coding for noisy channels 
      Xu, Qian (Texas A&M University, 2005-11-01)
      The growing popularity of video sensor networks and video celluar phones has generated the need for low-complexity and power-efficient multimedia systems that can handle multiple video input and output streams. While ...
    • Layered Wyner-Ziv video coding for transmission over unreliable channels 
      Xu, Qian; Stankovic, Vladimir M.; Xiong, Zixiang (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2011-12-06)
      A system and method for video coding. Energy-concentrating transform operations are performed on video data to obtain transformed data. Nested scalar quantization is performed on the transformed data to generate blocks of ...
    • Layered Wyner-Ziv video coding: a new approach to video compression and delivery 
      Xu, Qian (2009-05-15)
      Following recent theoretical works on successive Wyner-Ziv coding, we propose a practical layered Wyner-Ziv video coder using the DCT, nested scalar quantiza- tion, and irregular LDPC code based Slepian-Wolf coding (or ...
    • Roles of Inositol-Requiring Enzyme 1 Alpha (IRE1α) in Odontogenesis 
      Xu, Qian (2022-07-26)
      Dentin sialophosphoprotein (DSPP) is highly expressed in odontoblasts that form dentin, and mutations in the DSPP gene are associated with dentinogenesis imperfecta (DGI)/dentin dysplasia (DD), which are the most common ...
