We tracked the points-of-gaze of human observers as they viewed videos drawn from foreign films while engaged in two different tasks: (1) Quality Assessment and (2) Summarization. Each video was subjected to three possible distortion severities – no compression (pristine), low compression and high compression – using the H.264 compression standard. We have analyzed these eye-movement locations ...

This study evaluates the effect of internal neurolysis on a chronically compressed primate median nerve as compared with a simple decompression procedure. In 11 adult, cynomologous monkeys, the median nerve in the carpal tunnel was banded with a silicone tube. After 6 months of nerve compression (mild to moderate compression in our model) in eight monkeys, a microneurosurgical internal neurolys...

BACKGROUND In a rodent model of cardiac arrest and resuscitation in which the inspired gas mixture was enriched with oxygen, resuscitability and survival were unaffected by positive pressure ventilation. In the present study, in a larger animal model, tidal volumes generated during precordial compression and with spontaneous gasping were quantitated. METHODS Domestic pigs with an average weig...

This paper presents a new compression algorithm for 3D dynamic mesh sequences based on the local principal component analysis (LPCA). The algorithm clusters the vertices into a number of clusters using the local similarity between the trajectories in a coordinate system that is defined in each cluster, and thus transforms the original vertex coordinates into the local coordinate frame of their ...

In recent past, vector quantization has been observed as an efficient technique for image compression. In general, image compression reduces the number bits required to represent an image. The main significance of image compression is that the quality of the image is preserved. This in turn increases the storage space and thereby the volume of the data that can be stored. Image compression is t...
