A fast and #exible multiresolution snake with a de"nite termination criterion
نویسندگان
چکیده
This paper describes a fast process of parametric snake evolution with a multiresolution strategy. Conventional parametric evolution method relies on matrix inversion throughout the iteration intermittently, in contrast the proposed method relaxes the matrix inversion which is costly and time consuming in cases where the resulting snake is #exible. The proposed method also eliminates the input of snake rigidity parameters when the snake is #exible. Also, a robust and de"nite termination criterion for both conventional and proposed methods is demonstrated in this paper. 2001 Pattern Recognition Society. Published by Elsevier Science Ltd.

A fast and flexible multiresolution snake with a definite termination criterion
This paper describes a fast process of parametric snake evolution with a multiresolution strategy. Conventional parametric evolution method relies on matrix inversion throughout the iteration intermittently, in contrast the proposed method relaxes the matrix inversion which is costly and time consuming in cases where the resulting snake is exible. The proposed method also eliminates the input o...
متن کاملALGEBRAS WITH CYCLE-FINITE STRONGLY SIMPLY CONNECTED GALOIS COVERINGS
Let $A$ be a nite dimensional $k-$algebra and $R$ be a locally bounded category such that $R rightarrow R/G = A$ is a Galois covering dened by the action of a torsion-free group of automorphisms of $R$. Following [30], we provide criteria on the convex subcategories of a strongly simply connected category R in order to be a cycle- nite category and describe the module category of $A$. We p...
متن کاملMultiresolution on compact groups
Given a compact group M, we de®ne the notion of multiresolution of L2 M with respect to an in®nite sequence of subgroups G0 G1 G2 such that G [k0Gk is a dense subgroup of M. We give characterizations of various axioms of multiresolution, demonstrate the existence and give the construction of a wavelet basis for L2 M. We also construct stationary multiresolution and wavelets from cyclic vec...
متن کاملOn the Graphs Related to Green Relations of Finite Semigroups
In this paper we develop an analog of the notion of the con- jugacy graph of nite groups for the nite semigroups by considering the Green relations of a nite semigroup. More precisely, by de ning the new graphs $Gamma_{L}(S)$, $Gamma_{H}(S)$, $Gamma_{J}(S)$ and $Gamma_{D}(S)$ (we name them the Green graphs) related to the Green relations L R J H and D of a nite semigroup S , we first atte...
متن کاملDynamical Control of Computations Using the Family of Optimal Two-point Methods to Solve Nonlinear Equations
One of the considerable discussions for solving the nonlinear equations is to find the optimal iteration, and to use a proper termination criterion which is able to obtain a high accuracy for the numerical solution. In this paper, for a certain class of the family of optimal two-point methods, we propose a new scheme based on the stochastic arithmetic to find the optimal number of iterations in...
