    • Value-Deviation-Bounded Serial Data Encoding for Energy-Efficient Approximate Communication 

      Stanley-Marbell, Phillip; Rinard, Martin (2015-06-04)
      Transferring data between ICs accounts for a growing proportion of system power in wearable and mobile systems. Reducing signal transitions reduces the dynamic power dissipated in this data transfer, but traditional ...
    • Variable Precision Logic 

      Michalski, Ryszard S.; Winston, Patrick H. (1985-08-01)
      Variable precision logic is concerned with problems of reasoning with incomplete information and under time constraints. It offers mechanisms for handling trade-offs between the precision of inferences and the ...
    • The Variational Approach to Shape from Shading 

      Horn, Berthold K.P. (1985-03-01)
      We develop a systematic approach to the discovery of parallel iterative schemes for solving the shape-from-shading problem on a grid. A standard procedure for finding such schemes is outlines, and subsequently used ...
    • A Vector Signal Processing Approach to Color 

      Sung, Kah-Kay (1992-01-01)
      Surface (Lambertain) color is a useful visual cue for analyzing material composition of scenes. This thesis adopts a signal processing approach to color vision. It represents color images as fields of 3D vectors, from ...
    • Vector-Based Integration of Local and Long-Range Information in Visual Cortex 

      Somers, David C.; Todorov, Emanuel V.; Siapas, Athanassios G.; Sur, Mriganka (1996-01-18)
      Integration of inputs by cortical neurons provides the basis for the complex information processing performed in the cerebral cortex. Here, we propose a new analytic framework for understanding integration within ...
    • Vectorizing Face Images by Interpreting Shape and Texture Computations 

      Beymer, David (1995-09-01)
      The correspondence problem in computer vision is basically a matching task between two or more sets of features. In this paper, we introduce a vectorized image representation, which is a feature-based representation where ...
    • Velocity Space and the Geometry of Planetary Orbits 

      Abelson, Harold; diSessa, Andrea; Rudolph, Lee (1974-12-01)
      We develop a theory of orbits for the inverse-square central force law which differs considerably from the usual deductive approach. In particular, we make no explicit use of calculus. By beginning with qualitative ...
    • Verb Classes and Alternations in Bangla, German, English, and Korean 

      Jones, Douglas A.; Berwick, Robert C.; Cho, Franklin; Khan, Zeeshan; Kohl, Karen T.; e.a. (1996-05-06)
      In this report, we investigate the relationship between the semantic and syntactic properties of verbs. Our work is based on the English Verb Classes and Alternations of (Levin, 1993). We explore how these classes are ...
    • Verifiably Secure Devices 

      Lepinski, Matt; Micali, Silvio; Izmalkov, Sergei (2007-12-05)
      We put forward the notion of a verifiably secure device, in essence a stronger notion of secure computation, and achieve it in the ballot-box model. Verifiably secure devices1. Provide a perfect solution to the problem of ...
    • Verification of Semantic Commutativity Conditions and Inverse Operations on Linked Data Structures 

      Kim, Deokhwan; Rinard, Martin C. (2010-12-03)
      Commuting operations play a critical role in many parallel computing systems. We present a new technique for verifying commutativity conditions, which are logical formulas that characterize when operations commute. Because ...
    • Verifying Quantitative Reliability of Programs That Execute on Unreliable Hardware 

      Carbin, Michael; Misailovic, Sasa; Rinard, Martin (2013-06-19)
      Emerging high-performance architectures are anticipated to contain unreliable components that may exhibit soft errors, which silently corrupt the results of computations. Full detection and recovery from soft errors is ...
    • Verifying the Correctness of Wide-Area Internet Routing 

      Feamster, Nick; Balakrishnan, Hari (2004-05-17)
      Several studies have shown that wide-area Internet routing is fragile, with failures occurring for a variety of reasons. Routing fragility is largely due to the flexible and powerful ways in which BGP can be configured to ...
    • Versatility and VersaBench: A New Metric and a Benchmark Suite for Flexible Architectures 

      Rabbah, Rodric M.; Bratt, Ian; Asanovic, Krste; Agarwal, Anant (2004-06-14)
      For the last several decades, computer architecture research has largely benefited from, and continues to be driven by ad-hoc benchmarking. Often the benchmarks are selected to represent workloads that architects believe ...
    • Vertical Image Registration in Stereopsis 

      Nielsen, K.R.K.; Poggio, T. (1983-10-01)
      Most computational theories of stereopsis require a registration stage prior to stereo matching to reduce the matching to a one-dimensional search. Even after registration, it is critical that the stereo matching process ...
    • Very Large Planner-Type Data Bases 

      McDermott, Drew V. (1975-09-01)
      This paper describes the implementation of a typical data-base manaer for an A.I. language like Planner, Conniver, or QA4, and some proposed extensions for applications involving greater quantities of data than usual. ...
    • Victim Migration: Dynamically Adapting Between Private and Shared CMP Caches 

      Zhang, MIchael; Asanovic, Krste (2005-10-10)
      Future CMPs will have more cores and greater onchip cache capacity. The on-chip cache can either be divided into separate private L2 caches for each core, or treated as a large shared L2 cache. Private caches provide low ...
    • Video Ergo Scio 

      Marr, David; Hewitt, Carl (MIT Artificial Intelligence Laboratory, 1973-11)
      An approach to vision research is described that combines ideas about low level processing with more abstract notions about the representation of knowledge in intelligent systems. A particular problem, of the representation ...
    • Video Matching 

      Sand, Peter; Teller, Seth (2004-05-11)
      This paper describes a method for bringing two videos (recorded at different times) into spatiotemporal alignment, then comparing and combining corresponding pixels for applications such as background subtraction, compositing, ...
    • The Video Mesh: A Data Structure for Image-based Video Editing 

      Durand, Fredo; Cohen, Michael; Chen, Jiawen; Paris, Sylvain; Wang, Jue; e.a. (2009-12-16)
      This paper introduces the video mesh, a data structure for representing video as 2.5D "paper cutouts." The video mesh allows interactive editing of moving objects and modeling of depth, which enables 3D effects and ...
    • A View on Dyslexia 

      Geiger, Gad; Lettvin, Jerome Y. (1997-06-01)
      We describe here, briefly, a perceptual non-reading measure which reliably distinguishes between dyslexic persons and ordinary readers. More importantly, we describe a regimen of practice with which dyslexics learn a ...
