Detection of semantic objects using description graphs

Detection of semantic objects using description graphs
This paper presents a technique to detect instances of classes (objects) according to their semantic definition in the form of a Description Graph. Classes are defined as combinations of instances of lower level semantic classes and allow the definition of a Semantic Tree that organizes classes in semantic levels. At the bottom level of the Semantic Tree, classes are defined by a perceptual model containing a list of low-level descriptors. The proposed detection algorithm follows a bottom-up/top-down approach, building Semantic Trees on a region-based representation of the media. The flexibility of the approach is assessed on different examples of planar objects, such as frontal faces, groups of islands, flags and traffic signs.
