  • Development of Japanese-language DSP Education Content in the Connexions Project 

    Frantz, Patrick; Yamada, Yoji (2005-10-01)
    Due to factors such as a small and fragmented market and rapid hardware development, the conventional textbook is inadequate for DSP lab education. Freely available open-content materials that enable and promote local ...
  • Dialogue Concerning Neural Coding and Information Theory 

    Johnson, Don (2003-08-20)
    The relations between information theory and neural coding are discussed by two researchers, one knowledgeable in information theory, the other in neuroscience. The classic information-theoretic notions of entropy, mutual ...
  • A Different First Course in Electrical Engineering 

    Johnson, Don; Wise, J D (1998-05-20)
    Traditional introductory courses in electrical engineering are typically circuit theory courses, which may include both analog and digital hardware and possibly software. The alternatives have focused on how to teach (using ...
  • A Different First Course in Electrical Engineering 

    Johnson, Don; Wise, J D (1999-09-20)
    A Different Course in Electrical Engineering
  • Digital Signal Processing Structures: Block and Multidemensional Formulation and Distributed Arithmetic 

    Burrus, C. Sidney (1978-01-20)
    In this report we will consider a special class of digital filter structure; and by structure we mean the particular arrangement and sequence of arithmetic and storage operations to realize a desired signal processing ...
  • Directional Complex-Wavelet Processing 

    Fernandes, Felix; van Spaendonck, Rutger; Burrus, C. Sidney (2000-08-20)
    Poor directional selectivity, a major disadvantage of the separable 2D discrete wavelet transform (DWT), has previously been circumvented either by using highly redundant, nonseparable wavelet transforms or by using ...
  • Directional Hypercomplex Wavelets for Multidimensional Signal Analysis and Processing 

    Chan, Wai Lam; Choi, Hyeokho; Baraniuk, Richard G. (2004-05-01)
    We extend the wavelet transform to handle multidimensional signals that are smooth save for singularities along lower-dimensional manifolds. We first generalize the complex wavelet transform to higher dimensions using a ...
  • Directional Scale Analysis for Seismic Interpretation 

    van Spaendonck, Rutger; Baraniuk, Richard G. (1999-11-01)
    A combined space-Fourier representation focused on directional scale analysis is presented. The method leads to a space-log polar frequency distribution. Application to seismic data shows differentiation in scale and ...
  • Directional, Shift-Insensitive, Complex Wavelet Transforms with Controllable Redundancy 

    Fernandes, Felix (2001-08-20)
    Although the Discrete Wavelet Transform (DWT) is a powerful tool for signal and image processing, it has three serious disadvantages. First, the DWT is shift sensitive because input-signal shifts generate unpredictable ...
  • Discrete finite variation: A new measure of smoothness for the design of wavelet basis 

    Odegard, Jan E.; Burrus, C. Sidney (1996-05-20)
    A new method for measuring and designing smooth wavelet basis which dispenses with the need for having a large number of zero moments of the wavelet is given. The method is based on minimizing the "discrete finite variation", ...
  • Distributed Camera Network Localization 

    Mantzel, William; Choi, Hyeokho; Baraniuk, Richard G. (2004-11-01)
    Localization, estimating the positions and orientations of a set of cameras, is a critical first step in camera-based sensor network applications such as geometric estimation, scene reconstruction, and motion tracking. We ...
  • Distributed Compressed Sensing of Jointly Sparse Signals 

    Sarvotham, Shriram; Baron, Dror; Wakin, Michael; Duarte, Marco F.; Baraniuk, Richard G. (2005-11-01)
    Compressed sensing is an emerging field based on the revelation that a small collection of linear projections of a sparse signal contains enough information for reconstruction. In this paper we expand our theory for ...
  • Distributed Image Compression for Sensor Networks using Correspondence Analysis and Super-Resolution 

    Wagner, Raymond; Nowak, Robert David; Baraniuk, Richard G. (2003-09-01)
    We outline a distributed coding technique for images captured from sensors with overlapping fields of view in a sensor network. First, images from correlated views are roughly registered (relative to a sensor of primary ...
  • Distributed Image Compression in Camera Networks 

    Wagner, Raymond (2004-05-01)
    Dense networks of wireless, battery-powered sensors are now feasible thanks to recent hardware advances, but key issues such as power consumption plague widespread deployment. Fortunately, in a dense network of sensors, ...
  • Distributed Multiscale Data Analysis and Processing for Sensor Networks 

    Wagner, Raymond; Sarvotham, Shriram; Choi, Hyeokho; Baraniuk, Richard G. (2005-02-01)
    While multiresolution data analysis, processing, and compression hold considerable promise for sensor network applications, progress has been confounded by two factors. First, typical sensor data are irregularly spaced, ...
  • Distributed Wavelet Transform for Irregular Sensor Network Grids 

    Wagner, Raymond; Choi, Hyeokho; Baraniuk, Richard G.; Delouille, Veronique (2005-07-01)
    Wavelet-based distributed data processing holds much promise for sensor networks; however, irregular sensor node placement precludes the direct application of standard wavelet techniques. In this paper, we develop a new ...
  • Diverging moments and parameter estimation 

    Goncalves, Paulo; Riedi, Rudolf H. (2004-01-15)
    Heavy tailed distributions enjoy increased popularity and become more readily applicable as the arsenal of analytical and numerical tools grows. They play key roles in modeling approaches in networking, finance, hydrology ...
