چکیده

This paper introduces a novel approach for contour-based shape matching named as Constructive Relaxation Matching (CRM). In image matching relying on a particular modeling method, apparently similar images can be judged as being quite distant, according to the nature of the modeling process. In the proposed CRM, the modeling stage for a novel input image contour, commonly done in the same procedure used for modeling the templates, will be included in the procedure of iterative relaxation matching. Upon dynamically constructing the model during relaxation, pairs of contour objects having similar template label assignment probabilities will be unified to make one object. After describing the CRM procedures, the method is applied to simple shape matching problems demonstrating the ability to adaptively model the input image during relaxation. It is shown that the proposed CRM improves the object-label correspondence for evaluation of the image similarities in the following stages of shape matching applications.

Image Matching based on Relaxation and Model Switching on Contour Characterization

Relaxation labeling algorithms introduced by Rosenfeld et al., have been widely used in image and sequence matching applications. The underlying mechanism of labeling via relaxation is a deterministic dynamical system whose initial status converges to one of the attractors. This is also a process of the input image segments being assigned the predetermined labels in a parallel and unsupervised ...

A Novel Assisted History Matching Workflow and its Application in a Full Field Reservoir Simulation Model

The significant increase in using reservoir simulation models poses significant challenges in the design and calibration of models. Moreover, conventional model calibration, history matching, is usually performed using a trial and error process of adjusting model parameters until a satisfactory match is obtained. In addition, history matching is an inverse problem, and hence it may have non-uni...

A Bidirectional DC-DC Convreter with Zero Voltage Switching Capability for Energy Storage Application

In this paper, a bidirectional DC-DC converter with high power density for energy storage application is proposed. The presented converter provides power transfer in both directions only with adjusting phase shift angle. Zero voltage switching (ZVS) in both turn on and turn off moments of all switches is the major capability of the converter that makes it suitable for high power applications. Z...
