Automatic Matching Tool Selection

چکیده
For a given visual feature, due to the diversity of hu-man's subjective judgment, a visual information retrieval system that supports a single preexed similarity measure will result in poor retrieval performance. To address this problem, this paper proposes the concept of similarity matching toolkit which consists of different similarity measures simulating human's perceptions of the given feature from diierent aspects. The toolkit supports a feedback-driven tool selection mechanism which adapts to the similarity measure that best ts the user's perception. To illustrate the advantage of the proposed toolkit approach, we apply it to shape-based image retrieval. The paper describes a shape matching toolkit consisting of four transformation-invariant and computation-ally eecient matching tools and describes how relevance feedback can be used for automatic tool selection. Experimental results validate the exibility of the matching toolkit and show the eeectiveness of the relevance feedback for shape matching tool selection.

متن کاملFractured Reservoirs History Matching based on Proxy Model and Intelligent Optimization Algorithms
In this paper, a new robust approach based on Least Square Support Vector Machine (LSSVM) as a proxy model is used for an automatic fractured reservoir history matching. The proxy model is made to model the history match objective function (mismatch values) based on the history data of the field. This model is then used to minimize the objective function through Particle Swarm Optimization (...

A New Structural Matching Method Based on Linear Features for High Resolution Satellite Images
Along with commercial accessibility of high resolution satellite images in recent decades, the issue of extracting accurate 3D spatial information in many fields became the centre of attention and applications related to photogrammetry and remote sensing has increased. To extract such information, the images should be geo-referenced. The procedure of georeferencing is done in four main steps...
