  • Liu, Lifeng; Sclaroff, Stan (Boston University Computer Science Department, 1997-11-24)
    A new deformable shape-based method for color region segmentation is described. The method includes two stages: over-segmentation using a traditional color region segmentation algorithm, followed by deformable model-based ...
  • Sethi, Saratendu; Sclaroff, Stan (Boston University Computer Science Department, 1999-07-27)
    We propose to investigate a model-based technique for encoding non-rigid object classes in terms of object prototypes. Objects from the same class can be parameterized by identifying shape and appearance invariants of the ...
  • La Casica, Marco; Sethi, Sarathendu; Sclaroff, Stan (Boston University Computer Science Department, 1998-02-09)
    Some WWW image engines allow the user to form a query in terms of text keywords. To build the image index, keywords are extracted heuristically from HTML documents containing each image, and/or from the image URL and file ...
  • Fahmy, Amr; Heddaya, Abdelsalam (Boston University Computer Science Department, 1996-09-20)
    Communication and synchronization stand as the dual bottlenecks in the performance of parallel systems, and especially those that attempt to alleviate the programming burden by incurring overhead in these two domains. We ...
  • West, Richard; Fry, Gerald; Wong, Gary (Boston University Computer Science Department, 2005-02-23)
    Research on the construction of logical overlay networks has gained significance in recent times. This is partly due to work on peer-to-peer (P2P) systems for locating and retrieving distributed data objects, and also ...
  • Lapets, Andrei (CS Department, Boston University, 2010-03-15)
    A problem is in the class NP when it is possible to compute in polynomial time that a given solution corresponds to a given problem instance. Those problems for which it is possible to compute in polynomial time a solution ...
  • Donnelly, Kevin; Kfoury, Assaf; Lapets, Andrei (CS Department, Boston University, 2010-03-15)
    Interdomain routing on the Internet is performed using route preference policies specified independently and arbitrarily by each autonomous system (AS) in the network. These policies are used in the border gateway protocol ...
  • Kfoury, Assaf (Computer Science Department, Boston University, 2013-11-25)
    We present elements of a typing theory for flow networks, where “types”, “typings”, and “type inference” are formulated in terms of familiar notions from polyhedral analysis and convex optimization. Based on this typing ...
  • Fuller, Benjamin; Reyzin, Leonid (Computer Science Department, Boston University, 2011-01-07)
    We investigate how information leakage reduces computational entropy of a random variable X. Recall that HILL and metric computational entropy are parameterized by quality (how distinguishable is X from a variable Z that ...
  • Gabay, Yarom; Ocean, Michael J.; Kfoury, Assaf J.; Liu, Likai (Boston University Computer Science Department, 2006-02-06)
    Sensor applications in Sensoria [1] are expressed using STEP (Sensorium Task Execution Plan). SNAFU (Sensor-Net Applications as Functional Units) serves as a high-level sensor-programming language, which is compiled into ...
  • Rodeski, Vladimir; Mullally, William; Bellardine, Carissa; Lutchen, Kenneth; Betke, Margrit (Boston University Computer Science Department, 2005-07-07)
    A difficulty in lung image registration is accounting for changes in the size of the lungs due to inspiration. We propose two methods for computing a uniform scale parameter for use in lung image registration that account ...
  • Nagy, Sue; Bestavros, Azer (Boston University Computer Science Department, 1997-05-15)
    We propose and evaluate admission control mechanisms for ACCORD, an Admission Control and Capacity Overload management Real-time Database framework-an architecture and a transaction model-for hard deadline RTDB systems. ...
  • Crovella, Mark E.; Frangioso, Robert; Harchol-Balter, Mor (Boston University Computer Science Department, 1999-03-31)
    Under high loads, a Web server may be servicing many hundreds of connections concurrently. In traditional Web servers, the question of the order in which concurrent connections are serviced has been left to the operating ...
  • Papapetrou, Panagiotis (Boston University Computer Science Department, 2006-12-30)
    The problem of discovering frequent arrangements of temporal intervals is studied. It is assumed that the database consists of sequences of events, where an event occurs during a time-interval. The goal is to mine temporal ...
  • Isidoro, John; Sclaroff, Stan (Boston University Computer Science Department, 2003-12-02)
    Space carving has emerged as a powerful method for multiview scene reconstruction. Although a wide variety of methods have been proposed, the quality of the reconstruction remains highly-dependent on the photometric ...
  • Guo, Liang; Crovella, Mark; Matta, Ibrahim (Boston University Computer Science Department, 2001)
  • Itkis, Gene (Boston University Computer Science Department, 2003-02-11)
    We propose a new notion of cryptographic tamper evidence. A tamper-evident signature scheme provides an additional procedure Div which detects tampering: given two signatures, Div can determine whether one of them was ...
  • Bassem, Christine; Bestavros, Azer (Boston University Computer Science Department, 2009-05-28)
    Routing protocols for ad-hoc networks assume that the nodes forming the network are either under a single authority, or else that they would be altruistically forwarding data for other nodes with no expectation of a return. ...
  • West, Richard; Wong, Gary (Boston University Computer Science Department, 2005-02-23)
    This paper is centered around the design of a thread- and memory-safe language, primarily for the compilation of application-specific services for extensible operating systems. We describe various issues that have influenced ...
  • Akram, Wajeeh; Tiberii, Laura; Betke, Margrit (Boston University Computer Science Department, 2006-05-11)
    Many people suffer from conditions that lead to deterioration of motor control and makes access to the computer using traditional input devices difficult. In particular, they may loose control of hand movement to the extent ...
