Features are the key to object description Morphoscope povides a wide range of features for shape color and texture description. Since there are infinite variations of region description new featuress are added via the built-in language. In the example below the conv attribute is defined by a combination of the predefined perimeter and area features. In this example a simple interval search is then added in the TD: section. Beyond interval search Morphoscope provides other state-of-the-art classifiers on a point & click basis. Once features and classifier are selected they are used to query the repository.
