Analyzing scenery images by monotonic tree

Abstract: Content-based image retrieval (CBIR) has been an active research area in the last ten years, and a variety of techniques have been developed. However, retrieving images on the basis of low-level features has proven unsatisfactory, and new techniques are needed to support high-level queries. Research efforts are needed to bridge the gap between high-level semantics and low-level features. In this paper, we present a novel approach to support semantics-based image retrieval. Our approach is based on the monotoni… Show more

“…They propose the selection of the level lines that minimize the well known Mumford-Shah functional restricted to the tree of shapes. Finally, in [8] the authors use an alternative and independent formulation of the tree of shapes, the so-called Monotonic Tree. They define structural elements (some subsets of the tree) from which they extract certain features and classify them according to those features.…”

“…A unique and promising monotonic tree approach that models scenery images as discrete structural elements has been proposed recently to bridge the semantic gap in contentbased image retrieval [41]. Based on simple assumptions about the colour, location, harshness, and shape of scenery features, monotonic trees embody the domain knowledge about scenery images to classify image regions into eight scenery object types with high accuracy to support semantics-based image retrieval.…”

“…The recent monotonic tree approach [41] provides a unique framework for analysing scenery images. Based on a new concept of monotonic line, image data are progressively represented as hierarchies of structural elements, which are classified and clustered into semantic regions of sky, building, tree, waves, placid water, lawn, snow, and others with qualifying scores.…”

“…Much research has been done on problems of scene classification [1,2,5,8,9,12,13,14,16,18]. The majority of these systems employed a learning-by-example approach based on low-level vision features derived exclusively from scene content.…”
