RAJIV MEHROTRA Content - Based Image Modeling and Retrieval
نویسنده
چکیده
A database system models and manages an abstracted real world (or mini-world) pertinent to the problem at hand in terms of alphanumeric data. The semantic associated with any piece of alphanumeric data is known to or derived by the users of the database. This conventional approach to data modeling and management is not well suited for the effective management of imagery data. In an image database management system, the desired information/semantics associated with the imaged mini-world needs to be automatically (or semi-automatically) extracted and appropriately modeled to facilitate content-based retrieval and manipulation of data. In this article, the key issues in contentbased image data modeling and retrieval are discussed. A system called MUSEUM is briefly presented to illustrate some of the approaches used to resolve the main challenges of conent-based data modeling and retrieval.

Image retrieval using the combination of text-based and content-based algorithms
Image retrieval is an important research field which has received great attention in the last decades. In this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. For text-based features, keywords and for content-based features, color and texture features have been used. Query in this system contains some keywords and an input...
متن کاملContent Based Radiographic Images Indexing and Retrieval Using Pattern Orientation Histogram
Introduction: Content Based Image Retrieval (CBIR) is a method of image searching and retrieval in a database. In medical applications, CBIR is a tool used by physicians to compare the previous and current medical images associated with patients pathological conditions. As the volume of pictorial information stored in medical image databases is in progress, efficient image indexing and retri...
متن کاملGroup-of-Frames/Pictures Color Histogram Descriptors for Multimedia Applications
Joint representation of color-based features for multiple images or a video segment is an important task for visual information management systems. Generally, a key-frame or key-image is selected from such a group, and the color-related features of the entire collection are represented with those of the chosen sample. Such methods are highly dependent on the quality of the representative sample...
متن کاملSemiautomatic Image Retrieval Using the High Level Semantic Labels
Content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. The challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. Hence, in this paper, an image retrieval system is introduced that provided two kind of qu...
