Closing the loop: Detection and pursuit of a moving object by a moving observer
收藏 引用
IMAGE AND VISION computing 1996年 第4期14卷 265-275页
作者: Nordlund, P Uhlin, T Computational Vision and Active Perception Laboratory (CVAP) Department of Numerical Analysis and Computing Science Royal Institute of Technology S-100 44 Stockholm Sweden
We present an integrated system which is able to pursue a moving object and maintain the object centered in the image by controlling a robot-head. The system contains three parts: independent motion detection, trackin... 详细信息

Dynamic fixation and active perception
收藏 引用
INTERNATIONAL JOURNAL OF COMPUTER VISION 1996年 第2期17卷 113-135页
作者: Pahlavan, K Uhlin, T Eklundh, JO Computational Vision and Active Perception Laboratory (CVAP) Department of Numerical Analysis and Computing Science Royal Institute of Technology S-100 44 Stockholm Sweden
Fixation is the link between the physical environment and the visual observer, both of which can be dynamic. That is, dynamic fixation serves the task of preserving a reference point in the world, despite relative mot... 详细信息

Segmentation and classification of edges using minimum description length approximation and complementary junction cues
收藏 引用
COMPUTER VISION AND IMAGE UNDERSTANDING 1997年 第1期67卷 88-98页
作者: Lindeberg, T Li, MX Computational Vision and Active Perception Laboratory (CVAP) Department of Numerical Analysis and Computing Science Royal Institute of Technology S-100 44 Stockholm Sweden
This article presents a method for segmenting and classifying edges using minimum description length (MDL) approximation with automatically generated break points. A scheme is proposed where junction candidates are fi... 详细信息

INVESTIGATING SEMI-INFINITE PROGRAMS USING PENALTY-FUNCTIONS AND LAGRANGIAN-METHODS
收藏 引用
JOURNAL OF THE AUSTRALIAN MATHEMATICAL SOCIETY SERIES B-APPLIED MATHEMATICS 1986年 第2期28卷 158-169页
作者: GUSTAFSON, SA Department of Numerical Analysis and Computing Science The Royal Institute of Technology S-10044 Stockholm 70 Sweden.
In this paper the relations between semi-infinite programs and optimisation problems with finitely many variables and constraints are reviewed. Two classes of convex semi-infinite programs are defined, one based on th...

Active fixation for scene exploration
收藏 引用
INTERNATIONAL JOURNAL OF COMPUTER VISION 1996年 第2期17卷 137-162页
作者: Brunnstrom, K Eklundh, JO Uhlin, T Computational Vision and Active Perception Laboratory (CVAP) Department of Numerical Analysis and Computing Science KTH (Royal Institute of Technology) S-100 44 Stockholm Sweden
It is well-known that active selection of fixation points in humans is highly context and task dependent. It is therefore likely that successful computational processes for fixation in active vision should be so too. ... 详细信息

Machine vision research at CVAP: An introduction
收藏 引用
INTERNATIONAL JOURNAL OF COMPUTER VISION 1996年 第2期17卷 107-112页
作者: Eklundh, JO Computational Vision and Active Perception Laboratory (CVAP) Department of Numerical Analysis and Computing Science KTH (Royal Institute of Technology) S-100 44 Stockholm Sweden
This paper deals with the problems on the recovery and shape and motion. It also focuses on what is representing shape. In addition, it touches a briefly on the geometry for computer vision which concerns surface mode... 详细信息

Projectively invariant decomposition and recognition of planar shapes
收藏 引用
INTERNATIONAL JOURNAL OF COMPUTER VISION 1996年 第2期17卷 193-209页
作者: Carlsson, S Computational Vision and Active Perception Laboratory (CVAP) Department of Numerical Analysis and Computing Science KTH (Royal Institute of Technology) S-100 44 Stockholm Sweden
An algorithm is presented for computing a decomposition of planar shapes into convex subparts represented by ellipses, The method is invariant to projective transformations of the shape, and thus the conic primitives ... 详细信息

Shape-adapted smoothing in estimation of 3-D shape cues from affine deformations of local 2-D brightness structure
收藏 引用
IMAGE AND VISION computing 1997年 第6期15卷 415-434页
作者: Lindeberg, T Garding, J Computational Vision and Active Perception Laboratory (CVAP) Department of Numerical Analysis and Computing Science KTH (Royal Institute of Technology) S-100 44 Stockholm Sweden
This article describes a method for reducing the shape distortions due to scale space smoothing that arise in the computation of 3-D shape cues using operators (derivatives) defined from scale-space representation. Mo... 详细信息
