The phase computation is used in many applications of signal and image processing such as edge, line, symmetry detection, image analysis and recently to show small motion or color changes. Eulerian video processing allows to show small color changes and motions invisibles to the naked eye. Eulerian motion magnification, was modify using the phase and the Riesz pyramid in order to reduce the noi...

In this work, we present a registration framework for cardiac cine MRI (cMRI), tagged (tMRI) and delay-enhancement MRI (deMRI), where the two main issues to find an accurate alignment between these images have been taking into account: the presence of tags in tMRI and respiration artifacts in all sequences. A steerable pyramid image decomposition has been used for detagging purposes since it is...

We present ERSS 2005, our entry to this year’s DUC competition. With only slight modifications from last year’s version to accommodate the more complex context information present in DUC 2005, we achieved a similar performance to last year’s entry, ranking roughly in the upper third when examining the ROUGE-1 and Basic Element score. We also participated in the additional manual evaluation base...

We present an empirically grounded method for evaluating content selection in summarization. It incorporates the idea that no single best model summary for a collection of documents exists. Our method quantifies the relative importance of facts to be conveyed. We argue that it is reliable, predictive and diagnostic, thus improves considerably over the shortcomings of the human evaluation method...

storytelling. One of two methods was used for the storytelling: the Storyline method or the Associations Pyramid method. Seventy five-year-old children took part in the study. The results show that children are able to use different strategies to create a story together, the language and communication competence of the children is already well developed, and the children are ready for effective...

In evaluation of automatic summaries, it is necessary to employ multiple topics and human-produced models in order for the assessment to be stable and reliable. However, providing multiple topics and models is costly and time-consuming. This paper examines the relation between the number of available models and topics and the correlations with human judgment obtained by automatic metrics ROUGE ...

This paper presents a novel framework to encode a combinatorial pyramid. A combinatorial pyramid is a hierarchy of successively reduced combinatorial maps. Important properties of the combinatorial pyramids such as topology preservation, the process global and local features within the same data structure, etc. made them useful for image processing and pattern recognition tasks. Their advantage...

Robust scale estimation is a challenging problem in visual object tracking. Most existing methods fail to handle large scale variations in complex image sequences. This paper presents a novel approach for robust scale estimation in a tracking-by-detection framework. The proposed approach works by learning discriminative correlation filters based on a scale pyramid representation. We learn separ...

The 3D pyramid compressor project at the University of Glasgow has developed a compressor for images obtained from CLSM device. The proposed method using a combination of image pyramid coder and vector quantization techniques has good performance at compressing confocal volume image data. An experiment was conducted on several kinds of CLSM data using the presented compressor compared to other ...
