Semantic segmentation is challenging as it requires both object-level information and pixel-level accuracy. Recently, FCN-based systems gained great improvement in this area. Unlike classification networks, combining features of different layers plays an important role in these dense prediction models, as these features contains information of different levels. A number of models have been prop...

By combining X-ray and neutron diffraction with Raman and X-ray absorption spectroscopies, the location of vanadium in the structure of the Ba2In2-xVxO5+x solid solution and its local environment was evidenced. Vanadium is spread over the two Indium sites of the Brownmillerite structure but its surrounding is tetrahedral. This involves the introduction of oxygen vacancies in the “octahedral” la...

Users require to quickly and reliably process information in visually complex scenarios. Detecting changes in visual displays and tracking multiple moving targets are important in tasks ranging from surveillance, air traffic control and process management to gaming. By integrating depth information into visual displays we may alleviate some of the difficulties users face in these tasks. In this...

Bent-core molecules with a linear alkyl chain in the bay position (anchor shaped molecules) form new liquid crystalline phases combining periodicities with different coherence lengths in distinct directions; in these LC phases the molecules are organized on average orthogonal in modulated layers (ribbons or patches) with restricted rotation around the long axis, thus representing modulated SmA(...

A new method is proposed for eecient SNR scalability in predictive video coding. It is of low complexity, and it is applicable to standard DCT-based video compression with motion compensation. Information that is only available to the enhancement layers is exploited to improve the quality of their frame prediction without compromising the usefulness of the compressed data provided by the base l...

As a medium between people and the city, urbanscape makes a mental connection between individuals and their surroundings. It is usually difficult to conceive this mental relationship and its corresponding processes with usual methods. This study seeks to address the mental aspects of urbanscape and highlight its role and importance by using an innovative method. In this study, map-based meth...

We present a probabilistic approach to the segmentation of OCT scans of retinal tissue. By combining discrete exact inference and a global shape prior, accurate segmentations are computed that preserve the physiological order of intra-retinal layers. A major part of the computations can be performed in parallel. The evaluation reveals robustness against speckle noise, shadowing caused by blood ...

Solid-to-solid phase transition, although widely exploited in making new materials, challenges persistently our current theory for predicting its complex kinetics and rich microstructures in transition. The Ga2O3α-β phase transformation represents such a common but complex reaction with marked change in cation coordination and crystal density, which was known to yield either amorphous or crysta...
