Photobook: content-based manipulation of image databases

TL;DR: The Photobook system is described, which is a set of interactive tools for browsing and searching images and image sequences that make direct use of the image content rather than relying on text annotations to provide a sophisticated browsing and search capability.

Efficient and effective querying by image content

TL;DR: A set of novel features and similarity measures allowing query by image content, together with the QBIC system, and a new theorem that makes efficient filtering possible by bounding the non-Euclidean, full cross-term quadratic distance expression with a simple Euclidean distance.
Journal ArticleDOI

A graph distance metric based on the maximal common subgraph

TL;DR: It is formally shown that the new distance measure is a metric, based on the maximal common subgraph of two graphs, which is superior to edit distance based measures in that no particular edit operations together with their costs need to be defined.

Image query system and method

TL;DR: In this article, images in an image database are searched in response to queries which include the visual characteristics of the images such as colors, textures, shapes, and sizes, as well as by textual tags appended to the images.
Journal ArticleDOI

Visual image retrieval by elastic matching of user sketches

TL;DR: A technique which is based on elastic matching of sketched templates over the shapes in the images to evaluate similarity ranks and is integrated with arrangements to provide scale invariance and take into account spatial relationships between objects in multi-object queries.

R-trees: a dynamic index structure for spatial searching

TL;DR: A dynamic index structure called an R-tree is described which meets this need, and algorithms for searching and updating it are given and it is concluded that it is useful for current database systems in spatial applications.

Iconic Indexing by 2-D Strings

TL;DR: This approach allows an efficient and natural way to construct iconic indexes for pictures and proves the necessary and sufficient conditions to characterize ambiguous pictures for reduced 2D strings as well as normal 2-D strings.

Image database systems: A survey

TL;DR: The essential problems in IDB design are pointed out rather than classify the existing or proposed systems into an unestablished framework.
