New descriptors for image and video indexing
Résumé
In this chapter, we present new descriptors that were specifically developed for content-based image and video indexing and retrieval. The first ones are an extension of the descriptors proposed by Florack et al. and Schmid to the case of color images. They are suited for object recognition in still images. The second ones describe the global level of motion activity in an image sequence, and are a good complement to the traditional color and texture descriptors.
