The substance based picture recovery (CBIR) is a standout amongst the most famous, climbing exploration zones of the advanced picture handling. In this system, pictures are physically commented with catchphrases and afterward recovered utilizing content based hunt systems. The objective of CBIR is to concentrate visual substance of a picture immediately, for example color, surface, or shape. Th...

Content-based retrieval of multimedia information is one of the most difficult research topics in multimedia computing and information retrieval. In this paper, we present a visual system which allows content-based retrieval of still image. The recognition algorithms we used are based on spatio-temporal relations. Two approaches and algorithms were developed based on the similarity between poly...

Content-based image retrieval (CBIR) lets the user search an image database by means of image features rather than keywords. Although techniques for searching the database are quite advanced, the success of a CBIR system is still limited because few methods exists that close the gap between the semantics of the request and the features into which the request is to be translated. Progress can be...

This paper describes rate control algorithms that consider the trade-off between coded quality and temporal rate. We target improved coding efficiency for both frame-based and object-based video coding. We propose models that estimate the rate-distortion characteristics for coded frames and objects, as well as skipped frames and objects. Based on the proposed models, we propose three types of r...

Due to new techniques and new hardware capabilities image-based rendering (IBR) is not limited to offline rendering anymore. Today the use of pictures for complex 3d-models promises photo-realistic images even for realtime applications. This paper covers the various techniques which are capable of creating new perspectives in real-time. It also introduces a framework which enables the convenien...

The physical modeling of complex sound generators can only be approached by individually synthesizing and discretizing the objects that contribute to the generation of sounds. This raises the problem of how to correctly implement the interaction between these objects. In this article we show how to construct an object-based environment for sound generation, whose objects can be individually syn...

Video compression and retrieval have been treated as separate problems in the past. In this paper, we present an object-based video representation that facilitates both compression and retrieval. Typically in retrieval applications, a video sequence is subdivided in time into a set of shorter segments each of which contains similar content. These segments are represented by 2-D representative i...

Cognitive research indicates that multimedia presentations have benefits over text-only presentations, such as improved comprehension and recall by readers. In this paper, a method is proposed to enhance a text presentation with pictures, without using abstract semantic representations of either the text or the picture. The method is based on measuring similarity between the input text and text...

► Using two target out-groups we examined the effect of EBL on face processing. ► Out-group faces were processed faster with angry vs. happy EBL. ► In-group faces were processed faster with happy vs. angry EBL. ► Similar results were obtained using both Asian and Black targets. ► The phenomenon is likely due to an out-group, not a stereotyping, effect. a b s t r a c t a r t i c l e i n f o The ...

Abstrac t In this article we discuss a graphical, model-based reasoning environment for the acquisition of system design knowledge and use of this knowledge to perform model analysis, model simulation, and software synthesis. The environment consists of a graphical editor, a framework for adding new tools, and a collection of model-based reasoning tools. The graphical editor allows an analyst t...
