2D projection interval relationships: A symbolic representation of spatial relationships [chapter]

Mohammad Nabil, John Shepherd, Anne H. H. Ngu
1995 Lecture Notes in Computer Science  
Spatial relationships are important ingredients for expressing constraints in retrieval systems for spatial databases.  ...  We propose a graph representation for pictures that is based on 2D-PIR. This graph representation can be constructed e ciently and leads to an e cient algorithm for \picture matching".  ...  A s y m bolic picture is a digraph where nodes of the graph are symbols representing spatial objects and edges of the graph are labelled by 2D-PIR relationships.  ...

A multichannel storage arrangement scheme of pictorial databases for concurrent spatial match retrieval

Chin-Chen Chang, Jau-Ji Shen
2000 Computers and Mathematics with Applications  
When touching the applications related to pictorial databases, then the first problem that should be faced is the large amount of pictorial data (pictures) to be retrieved.  ...  of simple spatial match queries is minimized  ...  Figure 1 is a simple symbolic picture.

An Efficient Signature File Strategy for Similarity Retrieval from Large Iconic Image Databases

2002 Journal of Visual Languages and Computing  
In the previous signature-based approaches to retrieve symbolic pictures from a large iconic image database, only pictures of type-2 similarity are considered, where a picture A is of type-2 similarity  ...  Note that a picture is of type-0 similarity when all the spatial category relationships of each object pair are the same to the query picture, and a picture is of type-1 similarity when the picture is  ...  The symbol"denotes the 'at the same spatial location as' relationship and the symbol : denotes the 'in the same set as' relation.  ...
