Unified Pairwise Spatial Relations: An Application to Graphical Symbol Retrieval
نویسندگان
چکیده
In this paper, we present a novel unifying concept of pairwise spatial relations. We develop two way directional relations with respect to a unique point set, based on topology of the studied objects and thus avoids problems related to erroneous choices of reference objects while preserving symmetry. The method is robust to any type of image configuration since the directional relations are topologically guided. An automatic prototype graphical symbol retrieval is presented in order to establish its expressiveness.

Articulated Pose Estimation by a Graphical Model with Image Dependent Pairwise Relations
We present a method for estimating articulated human pose from a single static image based on a graphical model with novel pairwise relations that make adaptive use of local image measurements. More precisely, we specify a graphical model for human pose which exploits the fact the local image measurements can be used both to detect parts (or joints) and also to predict the spatial relationships...
متن کاملQualitative Spatial-Relation Reasoning for Design
Qualitative spatial relations are symbol abstractions of geometric representations, which allow computational analyses independent of, but consistent with, graphical depictions. This paper compiles some of the most commonly used sets of qualitative spatial relations and their logical inference mechanisms. The abstract representation of the relations’ interconnectedness in the form of their conc...
متن کاملMulti-Range Conditional Random Field for Classifying Railway Electrification System Objects Using Mobile Laser Scanning Data
Railway has been used as one of the most crucial means of transportation in public mobility and economic development. For efficiently operating railways, the electrification system in railway infrastructure, which supplies electric power to trains, is essential facilities for stable train operation. Due to its important role, the electrification system needs to be rigorously and regularly inspe...
متن کاملA graphical instrument for performance analysis of contractors
The relationship between the manufacturer and supplier has changed from one of competition into that of greater cooperation during recent years. The selection and evaluation of suppliers are primary and important issues when an enterprise implements Supplier Relationship Management (SRM) and Total Quality Management (TQM). Much research indicates that most enterprises tend to evaluate their sup...
متن کاملAn Intelligent Content-based Image Retrieval System based on Color, Shape and Spatial Relations
Content-based multimedia information retrieval is an interesting but difficult research. Current approaches include the use of color, texture, and shape information. In this paper, we present a hybrid approach, which incorporates color, shape and spatial relations among objects in a picture, to retrieve images from nearly 5000 pictures. A revised color scheme and its indexing technique are used...
