1315 be generally advocated, however, it would be necessary to study larger groups of patients and controls to determine the sensitivity and specificity ofthe test. Ironically, the diagnostic ( ‘gold”) standard against which the test results would be weighed would be clinical evaluation with reproduction of symptoms with hyperventilation. In the final analysis, therefore, I believe that the dia...

Computational models of the human visual system (HVS) play an instrumental role in the design and operation of numerous image and video processing algorithms. HVS models have proved beneficial not only for boosting an algorithm’s performance, but also for improving its reliability and robustness to changing conditions. Many processing algorithms operate on images and videos that are meant to be...

Herpesvirus saimiri (HVS) is a gamma herpesvirus with several properties that make it an amenable gene therapy vector; namely its large packaging capacity, its ability to persist as a nonintegrated episome, and its ability to infect numerous human cell types. We used RecA-mediated recombination to develop an HVS vector with a mutated virion protein. The heparan sulphate-binding region of HVS OR...

In this paper two new blind adaptive digital watermarking methods of color images are presented. The adaptability is based on perceptual watermarking which exploits Human Visual System (HVS) models. The first method performs watermark embedding in transform domain of DCT and the second method is based on DWT. Watermark is embedded into transform domain of a chosen color image component in a sel...

The Human Visual System (HVS) is a key part of the rendering pipeline. The human eye is only capable of sensing image detail in a 2◦ foveal region, relying on rapid eye movements, or saccades, to jump between points of interest. These points of interest are prioritised based on the saliency of the objects in the scene or the task the user is performing. These ”glimpses” of a scene are then asse...

By taking into account the properties and limitations of the human visual system (HVS), images can be more efficiently compressed, colors more accurately reproduced, prints better rendered, to mention a few major advantages. To achieve these goals it is necessary to build a computational model of the HVS. In this paper we give an introduction to the general issue of HVS-modeling and review the ...

BACKGROUND The success of mechanical clot retrieval for acute ischemic stroke may be influenced by the characteristics of the occlusive thrombus. The thrombus can be partly characterized by CT, as the hyperdense vessel sign (HVS) suggests erythrocyte-rich clot whereas fibrin-rich clot may be isodense. We hypothesized that the physical clot characteristics that determine CT density may also dete...

With more autonomous vehicles (AVs) being tested or deployed on public roads, human-driven (HVs) have to share the road with AVs. However, human drivers may not interact AVs same way as they HVs. Very few studies investigated drivers’ behaviors when sharing Based a real-world dataset, our study explored interactions in two types of events highway, i.e., car-following event and car-passing event...
