Assessing arterial-wall motion and deformations may reveal pathologic alterations in biomechanical properties of the parietal tissues and, thus, contribute to detection vascular disease onset. Ultrasound image sequences allow observation this many methods have been developed estimate temporal changes artery diameter wall thickness track 2-D displacements selected points. Some enable assessment ...

The aim of this study is to characterize and find the location of geological boundaries in different wells across a reservoir. Automatic detection of the geological boundaries can facilitate the matching of the stratigraphic layers in a reservoir and finally can lead to a correct reservoir rock characterization. Nowadays, the well-to-well correlation with the aim of finding the geological l...

Automatic Transcription of Polyphonic Musical Signals with Linear Matching Pursuit By Andrew McLeod The Harmonic Matching Pursuit (HMP) algorithm has offered promising results in the automatic transcription of audio signals. It works by decomposing the given signal into a set of harmonic atoms, and then grouping those atoms into individual notes. HMP has shown very promising results, but more r...

Automatic image measuring is to identify and to measure conjugate points in two or more overlapping photographs automatically. In digital photogrammetry, this process is done by image matching. A straightforward way to make image matching well-posed is to restrict the space of possible solutions and provide good initial parallax. Initial parallax is related to the searching space. The better th...
