On the Interaction between Object Recognition and Colour Constancy
(IEEE, 2003)
In this paper we investigate some aspects of the interaction between colour constancy and object recognition. We demonstrate that even under severe changes of illumination, many objects are reliably recognised if relying ...
Automatic FPGA based implementation of a classification tree
(IEEE, 2004)
We propose a method of automatic hardware implementation of a decision rule based on the Adaboost algorithm. We review the principles of the classification method and we evaluate its hardware implementation cost in term ...
Inter-stage Feature Propagation in Cascade Building with AdaBoost
(IEEE, 2004-08)
A modification of the cascaded detector with the Ada-Boost trained stage classifiers is proposed and brought to bear on the face detection problem. The cascaded detector is a sequential classifier with the ability of early ...
Epipolar Geometry Estimation via RANSAC Benefits from the Oriented Epipolar Constraint
(IEEE, 2004-08)
The efficiency of epipolar geometry estimation by RANSAC is improved by exploiting the oriented epipolar constraint. Performance evaluation shows that the enhancement brings up to a two-fold speed-up. The orientation test ...
On Combining Classifiers
(IEEE, 1998-03)
We develop a common theoretical framework for combining classifiers which use distinct pattern representations and show that many existing schemes can be considered as special cases of compound classification where all the ...
Using grammars for scene interpretation
(IEEE, 1996-09)
A method that employs grammars to direct the inference process of a vision system that does interpretation of dynamic scenes is described. The system uses a set of qualitative image descriptors to drive the interpretation. ...
Hypothesis selection for scene interpretation using grammatical models of scene evolution
(IEEE, 1998-08)
A major bottleneck in dynamic scene interpretation is the search that is required through a database to find a model that best matches the observed data. We show that the problem can be alleviated if the object model ...
Object-Detection With a Varying Number of Eigenspace Projections
(IEEE, 1998-08)
We present a method allowing a significant speed-up of the eigen-detection method (detection based on principle component analysis). We derive a formula for an upper bound on the class-conditional probability (or equivalently ...
Recognition Using Labelled Objects
(IEEE, 1998-08)
General object recognition is a difficult problem. We (1997) proposed a solution for object recognition in an unconstrained environment. We simplified the recognition problem by attaching a special planar pattern on objects ...
Dynamic Approximate Entropy Electroanatomic Maps Detect Rotors in a Simulated Atrial Fibrillation Model
(2014)
There is evidence that rotors could be drivers that maintain atrial fibrillation.
Complex fractionated atrial electrograms have been located in rotor tip areas.
However, the concept of electrogram fractionation, defined ...
