چکیده

A method for representing and matching logos based on positive and negative shape features is presented. Negative shape features represent an object that consists of several components enclosed in a simple geometric structure (e.g, a square) based on its interior with the components considered as holes. The goal is to find logos in a database that are most similar to a given sample logo. A border is added around logos that are not enclosed in a simple shape. Logos are segmented. Local and global shape features are computed for each component. Two methods for comparing logos represented by positive and negative components are presented and evaluated.

Matching of Polygon Objects by Optimizing Geometric Criteria

Despite the semantic criteria, geometric criteria have different performances on polygon feature matching in different vector datasets. By using these criteria for measuring the similarity of two polygons in all matchings, the same results would not have been obtained. To achieve the best matching results, the determination of optimal geometric criteria for each dataset is considered necessary....
