Shape from texture for smooth curved surfaces in perspective projection
收藏 引用
Journal of Mathematical Imaging and Vision 1992年 第4期2卷 327-350页
作者: Gårding, Jonas Computational Vision and Active Perception Laboratory (CVAP) Department of Numerical Analysis and Computing Science Royal Institute of Technology Stockholm S-100 44 Sweden
Projective distortion of surface texture observed in a perspective image can provide direct information about the shape of the underlying surface. Previous theories have generally concerned planar surfaces;this paper ... 详细信息

Majority gates vs. general weighted threshold gates
收藏 引用
Computational Complexity 1992年 第4期2卷 277-300页
作者: Goldmann, Mikael Håstad, Johan Razborov, Alexander Department of Numerical Analysis and Computing Science Royal Institute of Technology Stockholm S-100 44 Sweden Steklov Mathematical Institute Moscow 117966 GSP-1 Vavilova 42 Russian Federation
In this paper we study small depth circuits that contain threshold gates (with or without weights) and parity gates. All circuits we consider are of polynomial size. We prove several results which complete the work on... 详细信息

Modelling Hebbian cell assemblies comprised of cortical neurons
收藏 引用
Network: Computation in Neural Systems 1992年 第2期3卷 105-119页
作者: A Lansner E Fransen SANS—Studies of Artificial Neural Systems Department of Numerical Analysis and Computing Science Royal Institute of Technology S-l00 44 Stockholm Sweden
A highly simplified network model of cortical associative memory, based on Hebb's theory of cell assemblies, has been developed and simulated. The network comprises realistically modelled pyramidal-type cells and ...

A NEURAL NETWORK APPROACH TO STATISTICAL PATTERN-CLASSIFICATION BY SEMIPARAMETRIC ESTIMATION OF PROBABILITY DENSITY-FUNCTIONS
收藏 引用
IEEE TRANSACTIONS ON NEURAL NETWORKS 1991年 第3期2卷 366-377页
作者: TRAVEN, HGC Department of Numerical Analysis and Computing Science (NADA) Royal Institute of Technology Stockholm Sweden
The paper outlines a method for designing near optimal nonlinear classifiers based on a self-organizing technique for estimating probability density functions when only weak assumptions are made about the densities. T... 详细信息

On the power of small-depth threshold circuits
收藏 引用
Computational Complexity 1991年 第2期1卷 113-129页
作者: Håstad, Johan Goldmann, Mikael Department of Numerical Analysis and Computing Science Royal Institute of Technology Stockholm S-100 44 Sweden
We investigate the power of threshold circuits of small depth. In particular, we give functions that require exponential size unweighted threshold circuits of depth 3 when we restrict the bottom fanin. We also prove t... 详细信息

IMAGE AND VISION computing 1990年 第4期8卷 289-296页
作者: BRUNNSTROM, K EKLUNDH, JO LINDEBERG, T Computational Vision and Active Perception Laboratory Department of Numerical Analysis and Computing Science Royal Institute of Technology S-100 44 Stockholm Sweden
Focus-of-attention is extremely important in human visual perception. If computer vision systems are to perform tasks in a complex, dynamic world they will have to be able to control processing in a way that is analog... 详细信息

Annual IEEE Symposium on Foundations of Computer science
作者: J. Lagergren Department of Numerical Analysis and Computing Science Royal Institute of Technology Stockholm Sweden
An efficient parallel algorithm for the tree-decomposition problem for fixed width w is presented. The algorithm runs in time O(log/sup 3/ n) and uses O(n) processors on a concurrent-read, concurrent-write parallel ra... 详细信息

JOURNAL OF SYMBOLIC COMPUTATION 1988年 第1-2期5卷 131-140页
作者: ARNBORG, S FENG, H Department of Numerical Analysis and Computing Science The Royal Institute of Technology S-100 44 Stockholm Sweden
The cylindrical algebraic decomposition method decomposes E r into regions over which a given polynomial has constant sign by extension of one complicated decomposition of E r-1 . We investigate a method which decompo...
