2 D Projection Interval Relationships : A Symbolic
Spatial relationships are important ingredients for expressing constraints in retrieval systems for spatial databases. In this paper we propose a uniied representation of spatial relationships, 2D Projection Interval Relationships (2D-PIR), that integrates both directional and topological relationships. We propose a graph representation for pictures that is based on 2D-PIR. This graph represent...
متن کاملAn Image Retrieval System for Distributed Environments
In this paper, we describe a prototype image retrieval system for distributed environments based on 2D Projection Interval Relationships (2D-PIR). The system transforms an image to a symbolic representation that describes spatial relationships among objects in the image. The image database consists of three parts: the real image repository (which is distributed) and the symbolic and iconic imag...
متن کاملA Three-Dimensional Iconic Environment for Image Database Querying
Retrieval by contents of images from pictorial databases can be effectively performed through visual icon-based systems. In these systems, the representation of pictures with 2D strings, which are derived from symbolic projections, provides an efficient and natural way to construct iconic indexes for pictures and is also an ideai representation for the visual query. With this approach, retrieva...
متن کاملOn Completeness of Reasoning about Planar Spatial Relationships in Pictorial Retrieval Systems∗
In this paper we consider the completeness problem of reasoning about planar spatial relationships in pictorial retrieval systems. We define a large class of two-dimensional scenes, the extended pseudo-symbolic pictures. The existing rule system R is proved to be complete for (extended) pseudo-symbolic pictures. We also introduce a new iconic indexing, the (extended) pseudo2D string representat...
متن کامل∆-TSR: a description of spatial relationships between objects for image retrieval∗
This article presents ∆-TSR, a new image content representation exploiting the spatial relationships existing between its objects of interest. This approach provides two types of descriptions: with ∆-TSR3D, images are represented by geometric relationships between triplets of objects using triangle angles, while ∆-TSR5D enriches ∆-TSR3D by exploiting the orientation of the objects. The approach...
