Image Matching and Retrieval by Repetitive Patterns
(IEEE, 2010-08)
Detection of repetitive patterns in images has been studied for a long time in computer vision. This paper discusses a method for representing a lattice or line pattern by shift-invariant descriptor of the repeating element. ...
Wald’s Sequential Analysis for Time-constrained Vision Problems
(IEEE, 2007-04)
In detection and matching problems in computer vision, both classification errors and time to decision characterize the quality of an algorithmic solution. We show how to formalize such problems in the framework of sequential ...
Optimal Randomized RANSAC
(IEEE, 2008-08)
A randomized model verification strategy for RANSAC is presented. The proposed method finds, like RANSAC, a solution that is optimal with user-specified probability. The solution is found in time that is close to the ...
Multiview 3D Tracking with an Incrementally Constructed 3D Model
(IEEE, 2006-06)
We propose a multiview tracking method for rigid objects. Assuming that a part of the object is visible in at least two cameras, a partial 3D model is reconstructed in terms of a collection of small 3D planar patches of ...
Dense Linear-Time Correspondences for Tracking
(IEEE, 2008-06)
A novel method is proposed for the problem of frame-to-frame correspondence search in video sequences. The method, based on hashing of low-dimensional image descriptors, establishes dense correspondences and allows large ...
Geometric Hashing with Local Af ne Frames
(IEEE, 2006-06)
We propose a novel representation of local image structure and a matching scheme that are insensitive to a wide range of appearance changes. The representation is a collection of local affine frames that are constructed ...
Stable affine frames on isophotes
(IEEE, 2007-10)
We propose a new affine-covariant feature, the stable affine frame (SAF). SAFs lie on the boundary of extremal regions, i.e. on isophotes. Instead of requiring the whole isophote to be stable with respect to intensity ...
Randomized RANSAC with Sequential Probability Ratio Test
(IEEE, 2005-10)
A randomized model verification strategy for RANSAC is presented. The proposed method finds, like RANSAC, a solution that is optimal with user-controllable probability n. A provably optimal model verification strategy is ...
Epipolar Geometry from Two Correspondences
(IEEE, 2006)
A novel algorithm for robust RANSAC-like estimation of epipolar geometry (of uncalibrated camera pair) from two correspondences of local affine frames (LAFs) is presented. Each LAF is constructed from three points independently ...
