This paper addresses the problem of unsupervised TV programs structuring. Program structuring allows direct and non linear access to the desired parts of a program. Our work addresses the structuring of recurrent TV programs like news, entertainment programs, TV shows, TV magazines... In our previous work [1] we proposed a program structuring method based on the detection of video recurrences. ...

In the paper the implementation aspects of mathematical morphology based on a new formalization of the window operation is presented. The proposed technique called the Reverse Window Operation (RWO) can also be applied to adaptive morphological operations. In order to reduce the control complexity an algorithm is proposed, which uses a region-based parameter modiication for the structuring elem...

This paper proposes a fast algorithm for implementing the basic operation of Minkowski addition for the special case of binary three-dimensional (3-D) images, using 3-D structuring elements of arbitrary size and shape. The application of the proposed algorithm for all the other morphological transformations is straightforward, as they can all be expressed in terms of Minkowski addition. The eff...

Morphological tools can provide transformations suitable for real projective images, but the camera and objects to be analyzed have to be positioned in such a manner that a regular mesh on the objects projects a regular mesh on the image. A morphological modification of the image is thus the projection of an equivalent operation on the object. Otherwise, due to perspective effects, a morphologi...

During the past decade a number of modelling frameworks for knowledge based systems have been developed. In this paper an approach to the comparison of modelling frameworks is proposed, based on the aims and purposes behind the frameworks. A purpose oriented comparison of the frameworks DESIRE, CommonKADS, PROTÉGÉ-II, MIKE, VITAL and KARL provides insight in their differences and similarities.

In clinical research, the epidemiological design conforms the main part of the study plan and has an impact upon the set of options to be applied in the rest of the research protocol, referring to the selection of the patients, collection of the data and posterior analysis of the results. The design conditions the quality levels of the scientific evidence and the suitability of the recommendati...

Mathematical Morphology is a common strategy for non-linear filtering of image data. In its traditional form the filters used, known as structuring elements, have constant shape once set. Such rigid structuring elements are excellent for detecting patterns of a specific shape, but risk destroying valuable information in the data as they do not adapt in any way to its structure. We present a nov...

The decomposition of binary structuring elements is a key problem in morphological image processing. So far only the decomposition of convex structuring elements and of speciic subsets of non-convex ones have been proposed in the literature. This work presents the results of a new approach, based on a Genetic Algorithm, in which no constraints are imposed on the shape of the initial structuring...

This paper describes a problem-solving method for modelling the 'unprotocolised' treatment administration task in medicine. We argue that there are medical domains in which no well-established standard treatment protocols exist, and the physician has to decide on the therapy that is to be applied to each patient, in function of a set of therapeutic objectives to be fulfilled. For this reason, w...

pairing theory with methodology, this study demonstrates how efl teachers’ limited wait-time practice structures in and affects the structuring of the unfolding classroom discourse with reference to learners’ participation opportunities. informed by the tenets of conversation analysis, we have observed, videotaped, and transcribed line-by-line 10 efl teachers’ naturally-occurring classroom inte...
