Video inpainting software deletes people from HD video footage
In a development sure to send conspiracy theorists into a tizzy, researchers at the Max Planck Institute for Informatics (MPII) have developed video inpainting software that can effectively delete people or objects from high-definition footage. The software analyzes each video frame and calculates what pixels should replace a moving area that has been marked for removal. In a world first, the software can compensate for multiple people overlapped by the unwanted element, even if they are walking towards (or away from) the camera. See the incredible video demonstration after the break. View all The software was developed by a team led by Prof. The software was inspired by shift maps – which take a portion of footage from one moment in time and move it to another moment in time to fill in the occluded area.

Fabry–Pérot interferometer
Etalons are widely used in telecommunications, lasers and spectroscopy to control and measure the wavelengths of light. Recent advances in fabrication technique allow the creation of very precise tunable Fabry–Pérot interferometers. Basic description[edit] Fabry–Pérot interferometer, using a pair of partially reflective, slightly wedged optical flats. The wedge angle is highly exaggerated in this illustration; only a fraction of a degree is actually necessary. The heart of the Fabry–Pérot interferometer is a pair of partially reflective glass optical flats spaced millimeters to centimeters apart, with the reflective surfaces facing each other. In a typical system, illumination is provided by a diffuse source set at the focal plane of a collimating lens. Applications[edit] A picture of the solar corona taken with the LASCO C1 coronagraph which employed a tunable Fabry–Pérot interferometer to recover scans of the solar corona at a number of wavelengths near the FeXIV green line at 5308 Å.
Tree of Life Web Project
The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life.
Measuring carbon dioxide emissions with a portable spectrometer
18 February 2013, SPIE Newsroom. DOI: 10.1117/2.1201301.004659 Carbon dioxide (CO2) is the most important anthropogenic greenhouse gas influencing global warming. Earth surface monitoring points are concentrated in the mid-latitudes of the northern hemisphere (i.e., where most developed countries are situated). Figure 1. Our new spectrometer uses commercially available fiber optics and a fiber Fabry-Perot interferometer (FPI), that controls and measures light wavelengths. We can control the wavelengths of the solar spectrum that are transmitted through the fiber FPI by changing its temperature. Figure 2. We previously reported measurements of atmospheric CO2 columns made with a similar, precursor instrument at surface monitoring sites. Due to its portability, our fiber FPI instrument can be used to measure CO2 emissions from widely spread and unpredictable local sources, e.g., forest or peatland fires.

Top 10 Myths About Evolution - with Downloadable PDF | Atheism Resource - StumbleUpon
Email If you have been looking for a simple, easy to follow quick guide to evolution… we’ve got it. Our friends at the Skeptics Society gave us permission to reprint this. Below is the text. Learn it. Original Text: 1 If Humans Came From Apes, Why Aren’t Apes Evolving Into Humans? Humans, apes, and monkeys are only distant evolutionary “cousins.” 2 There Are Too Many Gaps in the Fossil Record for Evolution to Be True In fact, there are lots of intermediate fossils. 3 If Evolution Happened Gradually Over Millions of Years Why Doesn’t the Fossil Record Show Gradual Change? Sudden changes in the fossil record are not missing evidence of gradualism; they are extant evidence of punctuation. 4 No One Has Ever Seen Evolution Happen Evolution is a historical science confirmed by the fact that so many independent lines of evidence converge to this single conclusion. 5 Science Claims That Evolution Happens by Random Chance Natural selection is not “random” nor does it operate by “chance.”
