Formulation Detection and Localization criterions
, 1986
"... • Canny's aim was to discover the optimal edge detection algorithm: – good detection – the algorithm should mark as many real edges in the image as possible. – good localization – edges marked should be as close as possible to the edge in the real image. – minimal response – a given edge in the ..."

A local criterion for Tverberg graphs
, 2011
"... The topological Tverberg theorem states that for any prime power q and continuous map from a (d+ 1)(q − 1)simplex to Rd, there are q disjoint faces Fi of the simplex whose images intersect. It is possible to put conditions on which pairs of vertices of the simplex that are allowed to be in the same ..."

unions of small paths, cycles, and complete graphs are Tverberg graphs. We find many new examples by establishing a local criterion for a graph to be Tverberg. An easily stated corollary of our main theorem is that if the maximal degree of a graph is D, and D(D + 1) < q, then it is a Tverberg graph
A PERFORMANCE EVALUATION OF LOCAL DESCRIPTORS
, 2005
"... In this paper we compare the performance of descriptors computed for local interest regions, as for example extracted by the HarrisAffine detector [32]. Many different descriptors have been proposed in the literature. However, it is unclear which descriptors are more appropriate and how their perfo ..."

Local Criterion for Cleavage Fracture: Structural and Mechanical Approach
"... Abstract. On the base of physicalandmechanical modelling for cleavage microcrack behaviour a new local criterion for cleavage fracture is formulated. Cleavage fracture of pressure vessel steel under various loading history is investigated. It has been experimentally shown that for steels after sta ..."

A New Local Criterion for the Lattice Property
"... Abstract. We prove that a bounded poset of finite length is a lattice if and only if the following condition holds: whenever two elements x 1 , x 2 that cover a common element x are both smaller that two elements y 1 , y 2 that are covered by a common element y, then there exists an element z that ..."

of elements that cover a common element. In this note we give a new local criterion for the lattice property: it only considers two covers of an element x, which are both smaller than two cocovers of an element y, and requires that there is an element z between the two covers of x and the two cocovers of y
An InformationTheoretic Localization Criterion for Robot Map Building
, 1999
"... In the process of robot map building, many different aspects of the problem must be taken into account, like the environment the robot moves in, the type of sensors it uses, the dimensionality of the measurements, etc. One fundamental issue becomes the extraction of relevant features from the raw me ..."

Recently, a Bayesian localization error formula was proposed to be used as an optimization criterion in a neuralnetwork based nonlinear feature extraction scheme. We derive in this paper an alternative criterion for robot localization that is based
Region Competition: Unifying Snakes, Region Growing, and Bayes/MDL for Multiband Image Segmentation
 IEEE Transactions on Pattern Analysis and Machine Intelligence
, 1996
"... We present a novel statistical and variational approach to image segmentation based on a new algorithm named region competition. This algorithm is derived by minimizing a generalized Bayes/MDL criterion using the variational principle. The algorithm is guaranteed to converge to a local minimum and c ..."

Information flow and cooperative control of vehicle formations.

, 2002
"... Abstract We consider the problem of cooperation among a collection of vehicles performing a shared task using intervehicle communication to coordinate their actions. We apply tools from graph theory to relate the topology of the communication network to formation stability. We prove a Nyquist crite ..."

We also propose a method for decentralized information exchange between vehicles. This approach realizes a dynamical system that supplies each vehicle with a common reference
Local Criterion of Quality for Color Difference Formula

It is important to be equipped with criterion of correspondence between color difference formula and experimental data of color discrimination of standard observer considering a quality of color printing or measuring. Such criterion is used to distinguish whether applied color difference formula is ..."

Criterion of Local NonUniformity Every time we talk about precision of color reproduction and there is a necessity to numerically evaluate a value of error, we have to calculate a color difference. Since it was introduced in 1976, color difference
