Recall and precision are often used to evaluate the effectiveness of information retrieval
systems. They are easy to define if there is a single query and if the retrieval result generated for …

Images are being generated at an ever-increasing rate by sources such as defence and
civilian satellites, military reconnaissance and surveillance flights, fingerprinting and mug-shot-…

A sequential algorithm is presented for computing the exact Euclidean distance transform (DT)
of a k-dimensional binary image in time linear in the total number of voxels N. The …

Notations and definitions necessary to identify the concepts and relationships that are important
in modelling information retrieval objects and processes in the context of vector spaces …

Effective search and retrieval are enabling technologies for realizing the full potential of the
Web. The authors examine relevant issues, including methods for representing document …

When a query is submitted to a search engine, the search engine returns a dynamically
generated result page containing the result records, each of which usually consists of a link to …

In this paper, we present a comprehensive methodology for a formal, but intuitive, cause-effect
dependency modeling using multi-signal directed graphs that correspond closely to …

Similarity-based retrieval of images is an important task in many image database applications.
A major class of users' requests requires retrieving those images in the database that are …

Smartphones with megapixel cameras, handheld computers, wireless sensor networks,
ubiquitous social media, earth-orbiting satellites, space-bound telescopes—all generating more …

The Vector Space Model (VSM) has been adopted in information retrieval as a means of
coping with inexact representation of documents and queries, and the resulting difficulties in …
