  • Polimeni, Jonathan R.; Balasubramanian, Mukund; Schwartz, Eric L. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2006-06)
    We propose that a simple, closed-form mathematical expression--the Wedge-Dipole mapping--provides a concise approximation to the full-field, two-dimensional topographic structure of macaque V1, V2, and V3. A single map ...
  • Li, Rui; Sclaroff, Stan (Boston University Computer Science Department, 2004-11-02)
    Scene flow methods estimate the three-dimensional motion field for points in the world, using multi-camera video data. Such methods combine multi-view reconstruction with motion estimation approaches. This paper describes ...

    Scene flow methods estimate the three-dimensional motion field for points in the world, using multi-camera video data. Such methods combine multi-view reconstruction with motion estimation. This paper describes an alternative ...
  • Mingolla, Ennio; Neumann, Heiko; Pessoa, Luiz (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-02)
    A neural network model of brightness perception is developed to account for a wide variety of difficult data, including the classical phenomenon of Mach bands and nonlinear contrast effects associated with sinusoidal ...
  • Bestavros, Azer; Wang, Biao (Boston University Computer Science Department, 1993-10-27)
    This paper presents an algorithm which extends the relatively new notion of speculative concurrency control by delaying the commitment of transactions, thus allowing other conflicting transactions to continue execution and ...
  • Atlas, Alia; Bestavros, Azer (Boston University Computer Science Department, 1998-05-02)
    Quality of Service (QoS) guarantees are required by an increasing number of applications to ensure a minimal level of fidelity in the delivery of application data units through the network. Application-level QoS does not ...
  • Yuan, Quan; Thangali, Ashwin; Ablavsky, Vitaly; Sclaroff, Stan (Boston University Computer Science Department, 2008-06)
    Object detection is challenging when the object class exhibits large within-class variations. In this work, we show that foreground-background classification (detection) and within-class classification of the foreground ...
  • Gorman, Mikhail; Betke, Margrit; Saltzman, Elliot; Lahav, Amir (Boston University Computer Science Department, 2005-12-08)
    The therapeutic effects of playing music are being recognized increasingly in the field of rehabilitation medicine. People with physical disabilities, however, often do not have the motor dexterity needed to play an ...
  • Samz, Charles (International Center for East Asian Archaeology and Cultural History, Boston University, )
  • Aguilar, J. Mario; Contreras-Vidal, José L. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-10)
    A neural network system, NAVITE, for incremental trajectory generation and obstacle avoidance is presented. Unlike other approaches, the system is effective in unstructured environments. Multimodal inforrnation from visual ...
  • Potamias, Michalis; Bonchi, Francesco; Gionis, Aristides; Kollios, George (Boston University Computer Science Department, 2009-07-14)
    Large probabilistic graphs arise in various domains spanning from social networks to biological and communication networks. An important query in these graphs is the k nearest-neighbor query, which involves finding and ...
  • Rosengaus, Rebeca B.; Moustakas, Jacqueline E.; Calleri, Daniel V.; Traniello, James F.A. (University of Arizona Library, 2003-9-15)
    Termites form one-piece nests in wood that can vary in their moisture content and degree of decomposition, and thus microbial richness. To estimate the microbial load of nests and the potential risk they pose for colony ...
  • Londono, Jorge; Bestavros, Azer (Boston University Computer Science Department, 2006-12-15)
    Emerging configurable infrastructures such as large-scale overlays and grids, distributed testbeds, and sensor networks comprise diverse sets of available computing resources (e.g., CPU and OS capabilities and memory ...
  • Crovella, Mark; Barford, Paul (Boston University Computer Science Department, 1997-07-10)
    Prefetching has been shown to be an effective technique for reducing user perceived latency in distributed systems. In this paper we show that even when prefetching adds no extra traffic to the network, it can have serious ...
  • Fiala, John C. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-10)
    A model for self-organization of the coordinate transformations required for spatial reaching is presented. During a motor babbling phase, a mapping from spatial coordinate directions to joint motion directions is learned. ...
  • Day, John; Matta, Ibrahim; Mattar, Karim (Boston University Computer Science Department, 2008-08-15)
    This position paper outlines a new network architecture, i.e., a style of construction that identifies the objects and how they relate. We do not specify particular protocol implementations or specific interfaces and ...
  • Ulloa, Antonio; Bullock, Daniel (Boston University Computer Science Department, 2001-05)
    A neural network model is presented, that extends principles of the VITE (vector integration to end-point) model [1, 2, 3, 4] of primate reaching to the more complex case of reach-grasp coordination. The main new planning ...
  • Dessing, Joost; Bullock, Daniel; Peper, C. (Lieke); Beck, Peter (Boston University Computer Science Department, 2001-01)
    Two prospective controllers of hand movements in catching -- both based on required velocity control -- were simulated. Under certain conditions, this required velocity controlled to overshoots of the future interception ...
  • Cohen, Michael A.; Grossberg, Stephen; Pribe, Christopher (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-11)
    1) A large body of behavioral data conceming animal and human gaits and gait transitions is simulated as emergent properties of a central pattern generator (CPG) model. The CPG model incorporates neurons obeying Hodgkin-Huxley ...
