Processing similarity queries in mars
, 1997
"... To address the emerging needs of applications that require access to and retrieval of multimedia objects, we are developing the Multimedia Analysis and Retrieval System (MARS) in our group at the University of Illinois [13]. In this paper, we concentrate on the retrieval subsystem of MARS and its su ..."

support for content-based queries over image databases. Content-based retrieval techniques have been extensively studied for textual documents in the area of automatic information retrieval [24, 2]. This paper describes how these techniques can be adapted for ranked retrieval over image databases. Speci
Solving Approximate Similarity Queries
"... Abstract: Supporting similarity search capabilities in data repositories helps satisfy user information needs rather than only user data needs like conventional DBMSs. This is desired for many modern database applications. However, as the data repository contains high-dimensional data, solutions to ..."

to similarity search problem become cost-inefficient due to the so-called dimensionality curse. This phenomenon has been observed and shown that in high-dimensional data spaces the probability of overlaps between a query and data regions in a multidimensional access method (MAM) is very high. Hence
Distributed Processing of Similarity Queries
, 2001
"... Many modern applications in diverse fields demand the efficient manipulation of very large multidimensional datasets. It is evident, that efficient and effective query processing techniques need to be developed, in order to provide acceptable response times in query processing. In this paper, we stu ..."

study the processing of similarity nearest neighbor queries in large distributed multidimensional databases, where objects are represented as vectors in a vector space, and are distributed in a multi-computer environment. The departure from the centralized case embodies a number of advantages
Similarity Queries in Image Databases
- In CVPR'96 [5
, 1996
"... Query-by-content image database will be based on similarity, rater than on matching, where similarity is a measure that is defined and meaningful for every pair of images in the image space. Since it is the human user that, in the end, has to be satisfied with the results of the query, it is natural ..."

The Graphical Specification of Similarity Queries
- Journal of Visual Languages and Computing
, 1997
"... Image databases will require a completely new organization due to the unstructured and "perceptual" structure of the data they contain. We argue that similarity measures, rather than matching, will be the organizing principle of image databases. Similarity is a very elusive and complex ..."

derived from fuzzy logic in that it uses the equivalent in the similarity domain of the and, or, and not operations. The approach is much more general that that, however, and can be adapted to work with any operation that combines together similarity judgment. With this approach, a query can
Query language for complex similarity queries
- of Lecture Notes in Computer Science
, 2012
"... Abstract. For complex data types such as multimedia, traditional data management methods are not suitable. Instead of attribute matching ap-proaches, access methods based on object similarity are becoming pop-ular. Recently, this resulted in an intensive research of indexing and searching methods fo ..."

Approximate similarity queries: a survey
, 2001
"... We review the major paradigms for similarity queries, in particular those that allow approximate results. We propose an original classification schema which easily allows existing approaches to be compared along several independent coordinates, such as quality of results, error metrics, and user int ..."

Access Structures for Angular Similarity Queries
"... Abstract—Angular similarity measures have been utilized by several database applications to define semantic similarity between various data types such as text documents, time-series, images, and scientific data. Although similarity searches based on Euclidean distance have been extensively studied i ..."

for effective indexing methods for angular similarity queries. We first discuss how to efficiently process such queries and propose effective access structures suited to angular similarity measures. In particular, we propose two classes of access structures, namely, Angular-sweep and Cone-shell, which perform
Context-based Image Similarity Queries ⋆

By exploiting the notion of image “context”, it is possible to associate different meanings to the same query image. This is indeed necessary to model complex query concepts that, due to thei ..."
