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...

Abstract Cable-stayed bridges have gained greater coverage in the last few decades. This study focuses mainly on two parameters. Firstly, shape of pylons; performance many shapes is investigated after being exposed to an earthquake. Secondly, effect changing deck width inverted Y-shaped pylon with variation main span length. The numerical was performed using MIDAS civil software. It concluded t...

A distributed counter is a concurrent object which provides a fetch-and-increment operation on a shared value. On the basis of a distributed counter, one can implement various fundamental data structures, such as queues or stacks. We present the counting pyramid, an efficient implementation of a distributed counter in a message passing system, which is based on software combining. The counting ...

The proposed scheme of pyramid broadcasting is a new way of rendering Video On Demand service at metropolitan scale. In pyramid broadcasting, the most frequently requested movies are multiplexed on the broadcast network, resulting in radical improvement of access time and e cient bandwidth utilization. We provide analytical and experimental evaluations of pyramid broadcasting based on its imple...

as one of the most fundamental discourses of islamic humanism and islamic education system, inner nature (fiṭra) has always been of interest to muslim thinkers, philosophers, and educators. nevertheless, given the difference of the perspective and position that each thinker has adopted, various, and to some extent, different interpretations of fiṭra have been presented; therefore, the definitio...

Recently, we presented a new image pyramid, called the Riesz pyramid, that uses the Riesz transform to manipulate the phase in non-oriented sub-bands of an image sequence to produce real-time motion-magnified videos. In this report we give a quaternionic formulation of the Riesz pyramid, and show how several seemingly heuristic choices in how to use the Riesz transform for phase-based video mag...

In this paper we introduce a new type of Pascal’s pyramids. The new object is called hyperbolic Pascal pyramid since the mathematical background goes back to the regular cube mosaic (cubic honeycomb) in the hyperbolic space. The definition of the hyperbolic Pascal pyramid is a natural generalization of the definition of hyperbolic Pascal triangle ([2]) and Pascal’s arithmetic pyramid. We descri...
