One of the major obstacles towards the realization of automated creative design lies in the restricting design representation frames explicitly or implicitly imposed by common means for design representation. In this paper it is proposed to extend these frames by improving the design representation with a description technique that is more suitable to mimic some of the important cognitive proce...

Content based multimedia retrieval is an important topic in database systems. An emerging and challenging topic in this area is the content based search in video data. A video clip can be considered as a sequence of images or frames. Since this representation is too complex to facilitate efficient video retrieval, a video clip is often summarized by a more concise feature representation. In thi...

The dominant perspective on the representation of Africa in the western media claims that western media coverage is bias and crisis orientated and the liberal perspective claims that the coverage of Africa is not as negative as is often assumed. However, there is a paucity of literature on the representation of Africa online. This research enquiry is relevant because literature claims that the ...

This paper presents a novel approach for video-based person re-identification using multiple Convolutional Neural Networks (CNNs). Unlike previous work, we intend to extract a compact yet discriminative appearance representation from several frames rather than the whole sequence. Specifically, given a video, the representative frames are selected based on the walking profile of consecutive fram...

The use of frames and matching pursuits for signal representation are receiving increased attention due to their perceived potential in various signal processing applications. Good design algorithms for block oriented frames have recently been published. Viewing these block oriented frames as generalizations of block oriented transforms, it is natural to seek corresponding generalizations of cr...

This paper will look at the connection of operators and frames respectively related sequences from different viewpoints. We will give a survey of the classification of frames and similar sequences by the properties of the associated operators. Furthermore an important part will be the investigation of how to find a matrix representation of operators with Bessel sequences, frames and Riesz bases...

The demands placed on a knowledge representation scheme by a knowledge-based system are generally not all met by any of today’s candidates. Representation languages based on frames or semantic networks have intuitive appeal for forming descriptions but tend to have severely limited assertional power, and are often fraught with ambiguous readings. Those based on first-order logic are less limite...

We consider a generator F 1⁄4 ðf1; y ;fNÞ for either a multi-frame or a super-frame generated under the action of a projective unitary representation for a discrete countable group. Examples of such frames include Gabor multi-frames, Gabor super-frames and frames for shift-invariant subspaces. We show that there exists a unique normalized tight multi-frame (resp. super-frame) generator C 1⁄4 ðc...

This work proposes opinion frames as a representation of discourse-level associations which arise from related opinion topics. We illustrate how opinion frames help gather more information and also assist disambiguation. Finally we present the results of our experiments to detect these associations.

Frame knowledge representation systems lack two important capabilities that prevent them from scaling up to large applications: they do not support fast access to large knowledge bases (KBs), nor do they provide concurrent multiuser access to shared KBs. We describe the design and implementation of a storage subsystem that submerges a database management system (DBMS) within a knowledge represe...
