    • High Resolution MRI of Spinal Cords 
      Yu, Xiangdong; Li, Peng (2014-09-02)
      Spinal Cord Injury (SCI) is a common injury in incorrect sitting position, sports and car accidents. Noninvasive imaging methods play a critical role in diagnosing SCI and monitoring the response to therapy. Magnetic ...
    • Image Reconstructions of Compressed Sensing MRI with Multichannel Data 
      Chang, Ching-Hua (2016-05-06)
      Magnetic resonance imaging (MRI) provides high spatial resolution, high-quality of soft-tissue contrast, and multi-dimensional images. However, the speed of data acquisition limits potential applications. Compressed sensing ...
    • LDPC Codes over Large Alphabets and Their Applications to Compressed Sensing and Flash Memory 
      Zhang, Fan (2010-10-12)
      This dissertation is mainly focused on the analysis, design and optimization of Low-density parity-check (LDPC) codes over channels with large alphabet sets and the applications on compressed sensing (CS) and flash memories. ...
    • Low Power Approaches for Image Acquisition Systems 
      Gupta, Pravir (2020-07-15)
      This work presents novel image acquisition methodology to improve power and performance metrics of image acquisition system. Given the slowing Moore’s law, ubiquitous mobile devices like smartphones and focus on multimedia ...
    • Robustness of Compressed Sensing in Sensor Networks 
      Hern, Brett (2008-05-22)
      Compressed sensing is a new theory that is based on the fact that many natural images can be sparsely represented in an orthonormal wavelet basis. This theory holds valuable implications for wireless sensor networks ...
    • Spectral Estimation for Graph Signals Using Reed-Solomon Decoding 
      Deb, Abhishek (2017-07-21)
      Spectral estimation, coding theory and compressed sensing are three important sub-fields of signal processing and information theory. Although these fields developed fairly independently, several important connections ...
