Contextually Meaningful Representation of Color for the Description of Visual Content
نویسندگان
چکیده
A flexible framework for color representation is developed with the goal of lending perceptual or context specific meaning to visual content. Any given color representation in this framework consists of a set of definable base colors chosen from an underlying tri-chromatic color system. The mathematical foundation of the framework allows for a simple yet powerful assessment of visual similarity. A specific color representation within this framework is devised with the objective of enhancing content-based retrieval applications involving photographic content. Examples are presented and discussed.

We present here a prototype video analysis and retrieval system, called NeTra-V, that is being developed to build an object-based video representation for functionalities such as search and retrieval of video objects. A region-based content description scheme using low-level visual descriptors is proposed. In order to obtain regions for local feature extraction, a new spatio-temporal segmentati...
متن کاملContent based image retrieval and information theory: A general approach
A fundamental aspect of content-based image retrieval (CBIR) is the extraction and the representation of a visual feature that is an effective discriminant between pairs of images. Among the many visual features that have been studied, the distribution of color pixels in an image is the most common visual feature studied. The standard representation of color for content-based indexing in image ...
