In the paper a novel method for the estimation of the face recognition accuracy based on the modified Structural Similarity is presented. A typical application of the Structural Similarity index is related to the full-reference objective image quality assessment. Growing popularity of this metric is caused not only by the fact of its relatively low computational complexity but also by its sensi...

The digital image quality assessment is one of the most relevant aspects of contemporary digital image processing. A rapid development of some modern quality assessment techniques in recent years has caused the introduction of some new metrics, much better correlated with the Human Visual System (HVS) than the traditional ones such as the Mean Squared Error (MSE) or PSNR (Peak Signal to Noise R...

In a short speech aired on national television on August 9, US President George W. Bush announced that the National Institutes of Health (NIH) will be allowed to fund work with human embryonic stem (ES) cell lines — but only if the work involves lines that were established before the president’s announcement. The decision was greeted with measured optimism by many scientists, who await further ...

Lethal methods are important for predator management but new and innovative techniques may allow wildlife managers to reduce conflicts in ways that are most acceptable to the greatest number of people and optimize human-carnivore coexistence. Fladry is a suspended line of flagging used to exclude wolves from livestock; it has limited effectiveness because wolves habituate to the barrier. Electr...
