We consider a local least-squares criterion for aligning multiple time series fragments differing by locations and show the consistency of the time-lag estimator and the asymptotic normality of the location estimator. We apply the criterion to the problem of aligning 50 glacial varve fragments and construct a 3000-year surrogate for global temperature. Some key words: Aligning time series; Asym...

Aim of this paper is reformulation of global image thresholding problem as a well-founded statistical method known as change-point detection (CPD) problem. Our proposed CPD thresholding algorithm does not assume any prior statistical distribution of background and object grey levels. Further, this method is less influenced by an outlier due to our judicious derivation of a robust criterion func...

A novel and general criterion for image similarity validation is introduced using the so-called a contrario decision framework. It is mathematically proved that it is possible to compute a fully automatic detection criterion to decide that two images have a common cause, which can be taken as a de nition of similarity. Analytical estimates of the necessary and su cient number of sample points a...

We offer an equilibrium characterization of a general class of global games with strategic complementarities. The analysis highlights a form of acyclicity in the interim belief structure of global games, which allows us to formalize a selection criterion, iterated generalized half-dominance. This criterion is shown to be a unique global game selection when noise distributions satisfy a regulari...

This paper presents an improved segmentation approach derived from mean shift for natural images. The optimal color bandwidth under Plug-in rule is not always satisfying in the actual vision tasks, and a changing color bandwidth is helpful for controlling the segmentation result. The performance of direct density searching is better than mean shift under the same spatial bandwidth. A global opt...

In program slicing, widget-based event-driven programs are different from conventional programs because of their particular features of object construction infrastructure and event-driven mechanism and asynchronous access of global variables. Therefore conventional slicing techniques cannot be applied to widget-based event-driven programs. To solve this problem, this paper first introduces a se...

Pearl’s well-known d-separation criterion for an acylic directed graph (ADG) is a pathwise separation criterion that can be used to efficiently identify all valid conditional independence relations in the Markov model determined by the graph. This paper introduces p-separation, a pathwise separation criterion that efficiently identifies all valid conditional independences under the Andersson-Ma...

We study the evolution of a single crack in an elastic body and assume that the crack path is known in advance. The motion of the crack tip is modeled as a rate-independent process on the basis of Griffith’s local energy release rate criterion. According to this criterion, the system may stay in a local minimum before it performs a jump. The goal of this paper is to prove existence of such an e...
