Content-Based Image and Video Retrieval (Multimedia Systems by Oge Marques

By Oge Marques

Content-Based snapshot And Video Retrieval addresses the fundamental ideas and methods for designing content-based snapshot and video retrieval structures. It additionally discusses quite a few layout offerings for the main elements of those structures. This publication provides a entire survey of the content-based photo retrieval platforms, together with numerous content-based video retrieval platforms. The survey contains either study and advertisement content-based retrieval platforms. Content-Based photo And Video Retrieval comprises tips to 2 hundred consultant bibliographic references in this box, starting from survey papers to descriptions of modern paintings within the sector, complete books and greater than seventy web content. eventually, the booklet offers a close case learn of designing MUSE–a content-based snapshot retrieval method built at Florida Atlantic collage in Boca Raton, Florida.

Sample text

How can the system know which features to use or give preference to in a particular query? There are two possible ways of dealing with this issue: (a) Let the user explicitly indicate which features are important before submitting the query. This alternative is sometimes offered to the technical user in several CBIR systems working under the QBE paradigm. (b) Use machine learning techniques to understand the importance of each (set of) feature(s) based on the users' interactions and relevance feedback.

11 The measures to be used for evaluating system performance should include recall, precision, average number of stages for retrieving the relevant images, average rank of the relevant images, effectiveness of query language and model, effectiveness of relevance feedback. 12 Speed is not of central concern. While we clearly cannot ignore the speed of retrieval completely, it is primarily the software ability to identify visual information rather than the hardware efficiency that constitutes the main focus.

The most commonly used hardware-oriented color scheme for digital images. It preserves compatibility with the devices that originate or display images and is somewhat based on the physiology of the human retina. The RGB color space is represented as a unit cube. • CMY(K). The CMY color space is used for color printing. It is based on the three subtractive primary colors, Cyan, Magenta, and Yellow. Since most color printers are equipped with a black (K) cartridge in addition to the inks corresponding to the three primary colors, the model is sometimes referred to as CMYK.
